摘要：

This study presents a numerical analysis of a capillary pumped loop (CPL) performance using different working fluids and porous wick properties. A complete CPL model is used, which describes the growth of the vapor pocket inside the porous wick. The CPL behavior is studied for different working liquids, such as methanol, acetone and ethanol. Results show that methanol is the most efficient fluid in terms of thermal conductance and heat transport capacity. The present work allows also to evaluate the importance of the wick properties in the improvement of the thermal characteristics for capillary pumped loop. (C) 2016 Elsevier Ltd.
