Characterization of a Multiple-Evaporator Capillary Pumped Loop 2005-01-2884
The current work addresses efforts to characterize multiple-evaporator capillary pumped loops. Both experimental and analytical approaches were used to predict performance of parallel evaporators and corresponding effects from adjacent operating evaporators. The effects of low and high power dissipation and the distribution of powers among the evaporators were tested. Additionally, a pressure balance model is given where the maximum heat transfer capacity for an evaporator operating under a multi-evaporator condition is determined based on pressure distribution throughout the loop. The model and experiment comparisons demonstrated how the heat load distribution among evaporators affects the maximum capillary limit for individual evaporators operating in a multiple evaporator mode.
