This report presents a comprehensive analysis of heat exchanger performance, combining computational fluid dynamics (CFD) simulations using ANSYS with experimental data. The study investigates various heat exchanger designs, including aluminum and copper double pipe configurations in both parallel and counter-flow arrangements. The methodology involves CFD modeling, meshing, and post-processing to simulate heat transfer rates under different flow conditions (¼, ½, ¾, and full flow). Experimental data, including flow rates and temperatures, are collected and used to calculate key parameters such as the logarithmic mean temperature difference (LMTD) and heat transfer coefficients (U). The report provides a detailed comparison of numerical and experimental results, identifying potential sources of error and assessing the accuracy of the CFD simulations. The analysis also includes calculations of energy loss and gain, providing a thorough evaluation of heat exchanger efficiency. The findings offer valuable insights into the performance characteristics of different heat exchanger designs and operating conditions, contributing to a deeper understanding of heat transfer processes.
