Thermo-Mechanical Design of High Temperature Experimental Setup[ ]


Nuclear reactor generates heat which is used to generate electricity. Heat is produced by nuclear fission controlled reaction of U-235 at temperature ranges of 5500C - 20000C. According to first law of thermodynamics “Energy cannot be created Nor be destroyed, it can only be converted one form into another form”. Albert .E. Einstein proposed a law E=MC2 ,where mass ‘M’ of U-235 is converted into energy ‘E’ by bombardment of neutron travelling at speed of light ‘C’. The energy in form of heat produced is used to convert water into steam then produce electricity. The heat produced can cause thermal stresses in shell and tube. At a phase of shut down the power produced is only due to radioactive decay of nucleoid forms after bombardment of neutron. Neutrons have half-life of the 1000 second, after achieving saturation it emits continuous radiation of radioactive material. The decay power constituted 7% of total power produced by nuclear power plant. The production of radioactive materials violates the philosophy of level 3 & level 4 of defence in depth. So to prevents contamination of radioactive materials and production of decay power, ECCS (Emergency core cooling system) and ESF (Engineered safety feature) is designed to remove the decay heat under pipe break event and bring the increased fuel temperature to coolant temperature in present work it is planned to design an experimental setup to study the adequacy of ECCS injection to remove the decay power and cool the fuel pin simulator. As the test section temperature will be within 500oC hence the design will be done within elastic limit.

Development of Waterless Solar Panel Cleaner in Arid Areas[ ]


The solar panel is work by allowing the light into solar cells. The lighter that impact on a panel, the result more powers it will be generating. Due to the upwards angle of solar panels, they are more liable to a build up the dust and bird dropping. The dirt which is not clean with just rain. This is reducing the same amount of light impact on the panel and reducing panel output. The solar panel manufacturers and installers are claimed about the projected energy figures that based on the optimum performance of clean solar panel. Due to build up the dirt on solar panel, that can adversely affect the panel’s ability to meet that projected figures. So it is necessary and important to clean the solar panel in order to protect and get more power output. So we are design and develop the automatic machine which is clean the solar panel and improve the panel efficiency.

Study and Development of Automatic Retractable Bridge for Disabled People: A Review[ ]


The main aim of this project is to automate railway track pedestrian crossing without use staircase & announce the status of the arrival for platform users. In this system is also used to avoid train collision problems. Because, now a day train accidents are occurring frequently in India. The one of the main reason for train accident is the traveling of two trains in same track in opposite direction. In order to avoid the accidents due to the above reason we have designed this project. This project identifies the status of each train using IR transceivers and informs it to microcontroller. If the sensor unit identifies both train in same track means microcontroller automatically trip the supply of the trains, which is more than sufficient to avoid this kind of accident. This project is used to avoid the train collusion, thus we save the valuable human lives and losses. So this project is useful for railway departments.

Design and Modification of Camless Engine: A Review[ ]


The paper deals with The engines powering today’s vehicles whether they burn gasoline or diesel fuel rely on a system of valves to admit fuel and air into the cylinder and the exhaust gases to escape after combustion. Cam has been an integral part of internal combustion engine from its invention. Cam controls the breathing channels of the IC engines and hence maintains constant valve timing. The problem in using cam shafts is being major power wastage in accelerating and decelerating the components of the valve train. Friction of camshafts, springs, cam belts etc., also robs us of precious power and worsens fuel economy not to mention contributing to wear and tear. In response to the needs of improved engines some mechanical or hydraulic devices have been designed to achieve some variable valve timing and to reduce the disadvantages accompanied with the usage of cams. Most four-stroke piston engines today employ one or more camshafts operated poppet valves. The lobes on the camshafts operate cam followers which in turn open the poppet valves. A cam less (or, free valve engine) uses electromagnetic, hydraulic, or pneumatic actuators to open the poppet valves instead. Actuators can be used to both open and close the valves, or an actuator opens the valve while a spring closes it.

Self Inflation of Tyre[ ]


Studies have shown that due to drop in Tyre pressure by just a few PSI can result in reduction of tire life, gas mileage, and performance of vehicle. Also it can be the for road accidents. Though tubeless Tyres has been invented but it could not withstand as a perfect solution in all the conditions. So, we have developed automatic and self-inflated Tyresystem for stabilization of air in Tyres that ensures that Tyres are properly inflated all the times. This concept is based on the use of nozzle which helps to increase air thrust to overcome internal pressure of Tyre to regulate and maintain the Tyre pressure in running condition.The most important factors that should be taken in account for maintenance of Tyre like proper inflation pressure, proper vehicle loading, regular inspection, good driving habits, vehicle condition, etc.This concept arises with innovative idea for improvement in our Automobile industry. With the increasing prices of oil and growing concern of environmental issues, this system addresses a potential improvement in gas mileage. Thus in this concept, we reviewed the all available self-inflating Tyre systems that are used nowadays. There are lots of self-inflating-tire systems on the market, but most of them are only available for commercial and military application.

Experimental and Theoretical Investigation on Notched Specimens Life of Different Material by Experimental and Analytical Method[ ]


Fatigue is an important parameter to be considered in the behavior of mechanical components subjected to constant and variable amplitude loading. Mechanical, metallurgical and environmental variables can influence the fatigue resistance of a structural component. The number of cycles that a metal can endure before it breaks is a complex function of the static and cyclic stress values, the alloy, heat-treatment and surface condition of the material, the hardness profile of the material, impurities in the material, the type of load applied, the operating temperature, and several other factors. Various materials are subjected to different notch sizes and tested under bending loading for their endurance limit. These results obtained are then compared with their respective theoretical values obtained by The Modified Manson Coffin Curve Method.

Integrated Approach of Cost of Quality and Six Sigma[ ]


In today’s highly competitive markets high quality is critical for sustaining competitive advantage. Continuous quality improvement is a key factor in the strategy for competitiveness. Cost of Quality is one tool that can help in continuous quality improvement. To improve quality, an organization take into account the costs associated with achieving quality. It is often claimed by various researchers that the cost of quality stands for 10 to 40 percent of the company´s turnover, which is why it is important to measure and monitor COQ. This paper discusses recall of vehicles in India because of faulty design leading to heavy loss for the companies, accounting this cost of recall as quality cost. Automotive sector and the companies need to rethink and spend more time at the design and development phase where the problems could be envisaged in advance to avoid the quality cost. By implementing Six Sigma philosophy into manufacturing process, and or products, lower the quality cost and therefore overall cost. In the manufacturing process, six sigma capability and SPC tools helps to stop defects before they are created and helps to reduce the cost of poor quality.

Fabrication & Characterization of Pineapple Fiber Reinforced Epoxy Composite[ ]


This paper deals with the making of the biocomposite material which can replace the composite materials that are made from petroleum products. The bio-composite materials are made from natural materials which eco-friendly and can be easily used. Composite materials (also called composition materials or shortened to composites) are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter or less expensive when compared to traditional materials. In the last decades, the use of natural fibers as reinforcement in polymeric composites for technical application has been a research subject of scientist. Interest in natural fibers has increased worldwide due to their low cost, low density, hardness, higher fatigue endurance, good thermal and mechanical resistivity and to their environmental friendliness. The Asian markets have been using natural fibers for many years e.g., jute is a common reinforcement in India. Natural fibers are increasingly used in automotive and packaging materials. India is an agricultural country and it is the main stay of Indian economy. Thousands of tons of different crops are produced but most of their wastes do not have any useful utilization. Agricultural wastes include wheat husk, rice husk, and their straw, hemp fiber and shells of various dry fruits. These wastes can be used to prepare fiber reinforced polymer composites for commercial use.

The FMCG Packaging: Moving the Market towards Sustainable Packaging Materials[ ]


Sustainable packaging in the FMCG (fast moving consumer goods) market is moving from being purely cost driven towards a strategic approach of resource management. The principal purpose of packaging continues to be maintaining the safety, wholesomeness, and quality. The large growing middle class, liberalization and organized retail sector are the catalysts to growth in packaging. The key packaging materials are glass, metal, plastics, paper, laminates, co-extrusion and bio-degradable polymers. Being a cost-sensitive market, the pressure for FMCG companies to reduce packaging costs in India is strong. In the past 5-6 years the market for sustainable packaging in India was driven primarily by cost reduction, however, moving forward corporations are now placing more thought leadership into their sustainable packaging plans across the value chain. Indeed, packaging plays an essential role for FMCG businesses in meeting consumer needs and preventing waste by protecting products for proper consumption. The fast selling and low margin products have a high production and consumption rate, as well as, an extensive distribution network that demands large amount of paper/plastic/glass and metal. Sustainable packaging ultimately is the practice of ensuring any material waste from packaged products never leaves the value chain, as well as, uses material with little to zero environmental harm.

Optimization of Large Size Fabricated Y-Strainers for improvement in Pressure Drop Value using CFD Analysis: A Review[ ]


In the Oil & Gas Industry, an efficient filtration/separation system is critical to the reliability and performance of the physical assets that process petroleum products. Optimizing the reliability of these filtration systems is essential in maximizing your operational performance. Y-Type Strainers are used in many industrial applications to protect plant machinery to damage from contaminants such as dust, scales, sand, solid particles and other possibilities. It is used to remove solids from flowing gases or fluids using straining element. In this project a Y type strainer is considered for analysis. Design is an important industrial activity which influences the quality of the product. The strainer is modelled by using modelling software SolidWorks. By using this software, the time spent in producing the complex 3- D models and the risk involved in the design and manufacturing process can be easily minimized. So, the modelling of the strainer is to be made by using SolidWorks. Later this SolidWorks model will be imported to ANSYS WORKBENCH 14.5 for analysis work. ANSYS WORKBENCH 14.5 is the latest software used for simulating the different forces, pressure acting on the component and also calculating and viewing the results. By using ANSYS WORKBENCH 14.5 software reduces the time compared with the method of mathematical calculations by a human. Studies on flow behaviour in strainer has led to continued effort on optimizing the strainer design. 3D, steady, incompressible, turbulent k-∈ navier stokes equations are solved numerically to predict the flow behaviour and flow coefficient. CFD helps in the design optimization process with better accuracy and considerable reduction in design lead time. The present work aims to study the effect of pressure drop and flow behaviour across different strainer design. Based on the baseline simulation results, optimized design is suggested. The calculated pressure drop for the optimized design shows 30% improvement compared to baseline design.

Optimisation of Laser cutting on CFRP and Investigation of cutting parameters[ ]


This Research paper aims to study the effects of laser cutting/ drilling on a composite fiber reinforced polymer. It is super strong and light weighted material which has multiple applications. It is used in various industries such as aerospace, automobile and curl. CFRP has a very good strength to weight ratio. The conventional methods for CFRP is difficult but laser cutting offers an alternate method in which quality cut can be obtained by controlling different process parameters. Fibers are light weight, stiff, and strong, which provide most of stiffness and strength of the composite laminates. The polymer matrix binds the fibers together thus transferring load to reinforced fibers, and providing protection from environmental attack to fibers. Thermo set and thermoplastic are two kind of polymer matrix materials used most commonly. Thermoplastic polymers, however, are available which combine better mechanical properties, environmental resistance, temperature performance and processebility. Optimisation is possible on the basis of Taguchi method

Study of Gearbox Efficiency[ ]


There are many ways by which we can improve efficiency of gear. Many papers are published on efficiency of gear and gearbox. But these papers focuses on two or more parameters on which efficiency is depends such as noise, structure of gear, material used, lubrication, surface roughness, hardness etc. And methodology used for study of gearbox efficiency are FZG gear test rig, surface analysis, ANSYS etc. An effective method which focus on one parameter is required. Hence optimization of gearbox efficiency can be possible.
