用有限差分热传导程序HEATING一5~1模拟和计算了混合堆He冷却第一壁的热工水力问题,介绍了求解稳态、瞬态热传导方程的数值方法。为了解决程序中的热平衡方程没有包括流体的流动项问题,先用解析法计算冷却剂在不同流动位置的温度分布,用作程序的输入参数。同时,还用热平衡方程带有强迫对流项的有限元热传导程序计算了同一问题。其结果表明,用HEATING-5程序与AYER模拟冷却剂的强迫对流传热的计算结果符合得较好。
The finite element heat conduction program HEATING-5 ~ 1 was used to simulate and calculate the thermal-hydraulic problems of the first wall cooled by the mixed reactor He. The numerical method for solving steady-state and transient heat conduction equations was introduced. In order to solve the problem that the heat balance equation in the program does not include the flow of the fluid, the temperature distribution of the coolant at different flow locations is first calculated by the analytical method and used as the input parameter of the program. At the same time, the same problem is also solved by the finite element heat conduction program with a heat balance equation with forced convection term. The results show that the HEATING-5 program is in good agreement with the forced convection heat transfer of AYER simulation coolant.
