Numerical analysis on cooling capacity of transpiration cooling system

摘要: 以给定冷却工质质量流速下系统所能承受的最大热流表征冷却能力,对影响发散冷却系统冷却能力的主要因素进行了数值研究。理论分析和数值计算结果表明:发散冷却的冷却能力受冷却工质的吸热能力和冷却工质与固体骨架之间的换热能力共同制约。在小冷却工质质量流速下,发散冷却系统的冷却能力主要取决于冷却工质吸热能力,而随着冷却工质质量流速的增加,流固换热能力则逐渐成为决定冷却能力的主要因素,进而导致固体热导率和冷却工质比热容对发散冷却系统冷却能力的影响在不同冷却工质质量流速下存在显著差异。

Abstract: The maximum heat flux that the system can withstand under a specific amount of coolant consumption,was numerically investigated.The strict theoretical analysis and simulation results indicated that the transpiration cooling capacity was restricted by the coolant heat absorption capacity of the coolant and the heat exchange capacity between the fluid and solid.Under a small coolant mass flux,the transpiration cooling capacity was mainly determined by the coolant heat absorption capacity,while the effect of the heat exchange capacity between the fluid and solid on the transpiration cooling capacity increased with the coolant mass flux.Due to this crucial change,the effects of solid thermal conductivity,particle diameter of porous media and coolant specific heat on the transpiration cooling capacity under a small coolant mass flux were quite different with those under a larger coolant mass flux. -
