Transient Performance Prediction of EATHE System

In this book A numerical model has been developed to predict the EATHE transient thermal performance using Computational Fluid Dynamics (CFD) simulation tool and ‘Eureqa Formulize’ developed by Nutonian. Results of CFD simulations have been used as input data for Eureqa Formulize. The developed numerical model can be used to predict the thermal performance of an EATHE system operating under transient conditions (4 h to 16 h) for pipe diameter ranging between 0.1 to 0.2 m air flow velocity varying between 1 to 7 m/s. Developed correlation shows good agreement with the simulated data for the soil having thermal diffusivity between 1.37 × 10-7m2/s - 5.5 ×10 -7m2/s.
