Thermo-hydraulic performance comparison of steady laminar flow channels

Abstract

Thermo-hydraulic numerical analysis has been carried out to compare the characteristics of various shaped channels with two kinds of coolants such as EGW (EthyleneGlycol/Water) and PAO (PolyalphaOlefin). In this study, single-phase, constant property and threedimensional laminar forced convections are considered, and the governing differential equations for continuity, momentum, and energy transfer are solved computationally using the finitevolume method and the commercial codes of ICEPAK and FLUENT. The variations of the maximum temperatures as well as the temperature difference on the heat source surface with pumping power are compared depending on the coolants and channels.
