This paper presents a comparison of the experimental observations and numerical predictions for the thermal characteristics of the double pipe heat exchanger. A CAD design was developed and the Realizable k-ε mathematical model coupled with enhanced wall treatment gave the closest results. Experiments were performed for 60 ≤ Re ≤ 240 for two different inlet temperatures of the hot fluid, 50°C, and 70°C keeping the inlet temperature of the cold fluid constant at 31°C. Temperature gradients extracted from ANSYS Fluent were compared with the experimental data. Further, pressure and temperature contours for the hot and cold streams were generated to analyze the performance parameters.</p>}, number={2}, journal={Asian Review of Mechanical Engineering}, author={Kotian, Shreyas and Methekar, Nachiket and Jain, Nishant and Naik, Pritish}, year={2020}, month={Nov.}, pages={31–42} }
