Numerical Analysis of Heat Transfer of Hot Oil and Cold Water Fluids in a Concentric Type Heat Exchanger with Ansys Fluent

Abstract

In this study, the heat transfer performance of a trunk pipe heat exchanger using motor oil as hot fluid and cold water as cold fluid was analyzed by a compu-tational fluid dynamic (An-sys Fluent) program. The engine oil heat exchanger at different temperature rang-es (70C) and at different velocity (0.1m/s). Same case, the cold water at dif-ferent temperature ranges of the heat exchanger (5C) and different speed (1m/s) enters. The numerical re-sults and mesh validations are shown below.
