Abstract
The present study deals with the exergy modeling and simulation of a horizontal concentric tube heat exchanger. In this context, a fundamental thermodynamics-based exergy model is developed here to predict the irreversibility and entropy generation numberfor various fluid flow arrangements of a concentric tube heat exchanger. To develop the same, a second law of thermodynamics-based approach is utilized. Additionally, a finite volume method-based simulation of the same heat exchanger is also performed using a computer-aided engineering software named ANSYS R15.0. At last, the analytical and simulation results are compared and validated with experimental results, and a good agreement is achieved.
