摘要
内部再生冷却是一种新的推力室冷却技术,目前国内尚未采用.本文从物理模型及数学模型两方面研究了内部再生冷却机理,着重在不同边区冷却液流量、室壁材料和室壁厚度下进行了推力室壁的二维温度场的数值计算,并就计算结果作了分析和讨论.
The internal regenerative cooling is a new cooling technique of the thrust chamber.Up-to-date,it has not been used yet in our country.In this paper, a physical and mathematical model of the internal regenerative cooling is presented, and a numerical calculation of two-dimensional temperature field in the th-ruster wall is conducted emphatically under different parameters such as coolant flow rate near the wall, material and wall thickness.The calculation results are also analyzed and discussed.
