摘要

为了提升双层壁冷却系统性能并强化系统的冷却优势，将双层壁冷却系统的实体扰流柱结构替换为多孔介质结构，采用气热耦合方法数值研究了多孔介质结构对双层壁冷却系统的提升性能，分析并对比了不同吹风比、扰流柱直径与扰流柱高度对多孔介质结构和实体结构的流动及传热特性的影响规律。数值结果表明：对于多孔介质高渗透率结构，双层壁内、外壁面之间的速度和温度分布更加均匀；将实体扰流柱结构替换为多孔介质结构后，双层壁综合冷却有效度明显增大，面平均综合冷却有效度可提升3.08%~5.03%，而压力损失变化不大；随着多孔介质扰流柱直径的增大，综合冷却有效度呈现增大趋势，提升幅度为2.13%~3.03%；扰流柱高度对冷却性能的影响较为微弱。研究结果验证了多孔介质扰流柱在双层壁冷却系统中应用的可行性。

Abstract

To enhance the cooling performance of the double-wall cooling system and strengthen its cooling advantages

the solid pin fin structure of the system was replaced with a pin fin with porous medium

and the performance enhancement by the porous medium was investigated by using the conjugate heat transfer method. The differences in flow and heat transfer characteristics between porous medium and solid structures were studied in terms of different blowing ratios

pin fin diameters and pin fin heights. The results show that the velocity and temperature distributions between the inner and outer walls were more uniform under the high permeability properties of the porous medium. After the replacement

the overall cooling effectiveness was significantly improved

with an increase from 3.08% to 5.03% in area-averaged overall cooling effectiveness

while the pressure loss did not change much. As the diameter of the pin fin with the porous medium increased

the overall cooling effectiveness exhibited an increasing trend

ranging from 2.13% to 3.03%. The height of the pin fin had a weaker effect on the cooling performance. The applicability of porous media pin fins in a double-wall cooling system was verified.
