本文以一锥形复合防热套为研究对象，从烧蚀、隔热机理的理论分析和工艺试验两方面，进行了一下研究工作： 1 、通过对提高材料及制品通过对提高材料及制品隔热性能的多种途径进行探讨，提出了采用添加隔热功能层，研究复合型大面积防热套是理论有效、工艺可行的方案； 2 、通过建立有限元分析模型，对防热套的烧蚀隔热行为进行了理论分析，提出了简化的隔热计算方法，并用该方法对复合型防热套的瞬态传热模型进行了分析计算； 3 、通过复合型防热套的工艺探索试验，提出了一种工程应用上切实可行的工艺方案。 - The hot - dip - depth and temperature difference between fluid and platelet wall are influenced by many factors , such as the coefficient of heat conductivity of platelet and fluid , the coolant fluid , the knudsen number , and so on . high temperature make kn number become bigger , and then microscale effects become notable
3 、热浸深度、流体与层板壁面的温差大小要受层板的导热系数、冷却剂流量及流动的kn数等因素的影响。高温条件使kn数增大,微尺度效应增强;而高压条件下kn数减小,微尺度效应减弱。
