Abstract
Heat exchangers are used widely in many industries for heat recovery or
cooling purposes. This paper developed a numerical model to simulate a
counter flow parallel heat exchanger. A representative repeating unit cell
of the multi-channeled heat exchanger was taken as the computational
domain, which includes a cold channel and a hot channel separated by
plates. The model was simulated in COMSOL for an oil to water heat
exchanger. Higher temperature oil and relatively lower temperature
water entered two separate parallel channels in opposite directions. The
detailed distributions of temperature, velocity, and pressure were used to
analyze the performance of the heat exchanger. It was found the model
can be used to provide guidance for designing an optimal heat exchanger.
