Analysis of Earth Air Heat Exchanger (EAHE) for Storage system
Abstract: Geothermal energy is one of the potential alternative sources of energy which has been successfully catering to both industrial and domestic energy requirements. The temperature of earth at a certain depth about 2 to 5 m the temperature of ground remains nearly constant throughout the year. This constant temperature is called the undisturbed temperature of earth (EUT) which remains lower than the outside temperature in summer. In this research, a …

Design Fabrication and Testing of Hydraulic Oil Cooler by Using Heat Pipe
Abstract: Heat pipe is an essentially passive heat transfer device having high thermal conductivity. In hydraulic power pack use of traditional shell and tube heat exchanger would require lot of space, more power and maintenance cost. So heat pipe device is easily implemented for cooling of hydraulic oil. The heat pipe equipped hydraulic oil cooler uses a heat pipe module comprises of aluminum base block with oil channels machined on it. …

Dual Connection Pedal Powered Water Pumping System
Abstract: Now a days fossil fuels are going to empty in few year, so we have to again select the path of renewable energy. People are turning towards renewable energy sources like solar and wind and tidal etc. Human effort can also be considered the renewable source since it doesn’t use energy from non-renewable sources. There are many application of pedal power in our life. Many attempts are made to make …

INFLUENCE OF HEAT TREATMENT ON MECHANICAL PROPERTIES OF MILD STEEL
Abstract: . In manufacturing and metallurgical industries, the metal is heated above the critical temperature in which micro-structural transformation has been take place, to change the desirable microstructure and mechanical properties such as tensile strength, hardness, toughness, fatigue strength etc. The physical properties have been obtain through heat treatment mainly depends upon the heating temperature, rate of heating and the cooling medium. Some of the widely used cooling mediums are air, …

THERMAL DESIGN & THERMO STRUCTURAL ANALYSIS OF A PARTIAL ADMISSION TURBINE FOR UNDER WATER PROPULSION
Abstract: Underwater propulsion systems are gaining importance in recent years, various air-independent propulsion systems are being used for underwater applications. SCEPS (Stored Chemical Energy Propulsion System) for under water vehicles such as torpedoes use a compact steam turbine in closed loop. An attempt is made to optimize the design parameters for a partial admission impulse steam turbine and to maximize turbine efficiency. Thermo-structural analysis was also carried out in support to …
