Fluid Selection and Property Effects in Single-and Two-Phase Immersion Cooling

Abstract

A bslruct-The governing equations for liquid and two-phase heat transfer are used to derive fluid figures of merit (FOM’s) for forced and natural convection, boiling incipience, and critical heal flux in both pool and flow boiling modes. These FOM’s can he used to evaluate and compare the thermal performance of several candidate immersion cooling fluids. In addition, the governing equations are used to determine the sensitivities of thermal performance to fluid property values.
