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 computational fluid dynamic (Ansys Fluent) program. The engine oil heat exchanger at different temperature ranges (70˚C) and at different velocity (0.1m/s). Same case, the cold water at different temperature ranges of the heat exchanger (5°C) and different speed (1m/s) enters. The numerical results and mesh validations are shown below.
