对层板室壁中液态冷却剂的传热进行分析,得出影响层板室壁冷却效果的性能参数m1/2 ,该性能参数与层板通道换热面积、换热系数以及冷却剂比热有关,并以层板推力室为例,指出性能参数m1/2 对层板室壁内壁温度及内外壁温差的影响。
By analyzing the heat transfer of the liquid coolant in the wall of the lamina, we get the performance parameter m1 / 2 that affects the cooling effect of the lamina wall, which is related to the heat transfer area, the heat transfer coefficient and the specific heat of the coolant, Taking the laminar thrust chamber as an example, the influence of the performance parameter m1 / 2 on the temperature of the inner wall of the lamina wall and the temperature difference between the inner and outer walls is pointed out.
