“…This variation may be due to the coefficient of friction of the material which is used in simulation taken, irregularities such as insulation, and joints of experimental set-up [8]. CFD model of different diameters of chlorinated polyvinyl chloride pipes has been used for finding thermal performance of heat exchanger for the earth to air in a cooling mode where temperature fall has reduced while decreasing pip diameter and vice versa [9]. In this work, the CFD model of the earth air pipe heat exchanger has been used for finding thermal performance for building heating and cooling purposes.…”

The computational fluid dynamic (CFD) is an influential method for measuring Heat transfer profiles for typical meteorological years. CFD codes are managed by numerical algorithms that may undertake fluid glide headaches. CFD offers the numerical results of partial differential equations with main airflow and heat transfer in a discretized association. The complex fluid glide and the warmth transfer publications worried in any heat exchanger can be determined with the help of the CFD software program (Ansys Fluent). A study states and framework which implicitly rely on the computational fluid dynamics, which is being formulated for computing the efficiency-related parameters of the thermal part and the capability of the EATHE system for cooling. A CFD simulation program is being used for modeling the system. The framework is being validated with the help of the simulation set-up. A thermal model was developed to analyze thermal energy accumulated in soil/ground for the purpose of room cooling/heating of buildings in the desert (hot and dry) climate of the Bikaner region. In this study, the optimization of EATHE design has been performed for finding the thermal performance of straight, spiral, and helical pipe earth air tunnel heat exchanger and Heat transfer rate for helical pipe was found maximum among all designs.
