Cooling and Heating Effect of Geothermal Energy and Its Thermal Analysis Using Air as a Flow Medium

Sanjeev Patel, Abhishek Kumar

Abstract


Geothermal energy is one of the renewable sources of energy, which exists free in the environment. The main concept of a geothermal energy is the thermal energy of the ground which is used for cooling and heating. Here, air is used as a flow medium. The flow medium gets cool in the summer and gets heated in the winter due to the temperature difference between the flow medium and underground surface. Study of model is carried out using ANSYS software. Software simulation is being used for measurement of heat transfer. The software requires parameters, such as the diameter, air flow rate depth, tube length and condensation in the meantime have to be considered., Computational Fluid Dynamics (CFD Fluent) workbench under ANSYS software is used as simulation analysis. The parameters used for computation are the pipe of 45 m length, 0.004 m thickness and 0.08 m diameter. Velocity of air is considered to be 1 m/s and 5 m depth of pipe from the earth ground. The inlet temperature for a days in June (2016) to May (2017) according the climate of Algeria. Copper is considered for analysis. Using Fluent heat variations is being analyzed. It is observed at increasing velocity increases the rate of heat transfer, mid temperature, outlet temperature varies in summer and winter.
