SLHZC程序是一个用于水堆堆芯冷却剂流场、焓场分析的计算机程序。该程序以COBRA—ⅢC子通道分析程序为基础,物理模型较完善,数学上采用边值解法,可以处理较广泛的堆芯热工—水力问题。为了减少运算量和存贮量,本程序对上述程序做了某些改进,并增加了解入口压力边界条件问题的功能。给出了本程序部分计算结果的分析比较。
The SLHZC program is a computer program for the flow field and enthalpy analysis of coolant in a water reactor. The program is based on the COBRA-IIIC subchannel analysis program. Its physical model is perfect and its mathematical solution is the use of the boundary value method, which can handle a wider range of core thermal-hydraulic problems. In order to reduce the amount of computation and storage, the program made some improvements to the above procedures and added the function of understanding the boundary conditions of inlet pressure. The analysis and comparison of some calculation results of this program are given.
