静态超高压大腔体中热流的计算机模拟(Ⅰ)基本方程和数值求解方法

COMPUTER SIMULATION OF THE THERMAL FLOW INSIDE THE HIGH PRESSURE CELL(Ⅰ) EQUATIONS AND METHODS OF SOLUTION

对六面顶静态超高压大腔体中传热问题采用二维柱对称近似，提供一种能在计算机上实现的求瞬态和稳态温度分布的数值计算方法．估计了误差，推导了静态温度分布的近似解析表达式．

A two dimensional approximation with axisymmetry was used to deal with the thermal conduction inside the high pressure cell . A numerical method, using a microcomputer, to obtain the static and non steady distribution of temperature was given. The error of calculation in this method was estimated and an approximate analytical formula for the static distribution of the temperature was also given.
