He冷却混合堆第一壁的稳态、瞬态温度场计算

STEADY-AND TRANIENT-STATE TEMPERATURE FIELD CALCULATIONS OF A HE-COOLED FIRST WALL FOR FUSION BREEDER

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。

In this paper, a finite differential heat transfer computer code HEATING-5 has been used to model the thermal hydraulic problems of a He-cooled first wall for fusion breeder. The numerical techniquws of solving steady and transient state heat conduction equations are presented. The numerical calculations have been done. The temperature distributions of the coolant in different flow locations have been calcultaed by analytical method as the iuput parameters of the HEATING-5 code . in order go conform the fluid terms in the energy balance equation which are not included in the original code. Meanwhile , another finiteelement heat transfer computer code AYER , which includes forced convection flow terms in the heat transfer equation , is also used to solve the same problem . It shoes that the results by using HEATING -5 code to model coolant flow heat transfer are well consistent with that by using AYER code .
