Abstract

One of the main goals of a pumped two-phase flow cooling system is to ensure that there is a two phase flow at the exit of the cold plate so that the heat transfer coefficient remains very high. To decrease the mass flow rate but still prevent dryout, there is a motivation to maintain the exit quality at roughly 0.6 to 0.7 for an unknown time-varying heat load. In this paper, a simple output feedback control algorithm is proposed to achieve this goal. A nonlinear model based on the conservation of mass, momentum, and energy is used. Steady state solutions and their stability are analyzed. Results from numerical simulations with R134a flow corroborate the validity of the proposed novel feedback control algorithm.
