摘要
采用BETHSY自然循环实验数据对CATHARE2 V1.5qR6进行了评价。结果表明CATHRE2V1.5程序能较好地预测试验装置单相自然循环条件下的热工水力现象,对单相自然循环向两相自然循环的转变以及两相自然循环向回流冷凝运行方式的转变发生时的一回路水装量预测也比较准确,但对于两相自然循环及回流冷凝运行方式下系统的一些主要热工水力参数预测欠佳。评价结果表明,与许多国际性大型热工水力分析程序一样,CATHARE2V1.5qR6程序对剧烈两相流动的预测能力仍有待改进和完善。
The assessment of CATHARE2 V1. 5qR6 is carried out against the experimental data of BETHSY natural circulation test-4. la-TC. Results show that the experimental process under single phase natural circulation can be predicted very well by CATHARE2 V1. 5qR6,the primary mass inventory at the transition points from single phase natural circulation to two-phase natural circulation and from two-phase natural circulation to reflux condensation mode are also predicted correctly. The predicted results for thermohydraulic parameters of two-phase natural circulation and reflux condensation mode are not so good. Generally speaking, the prediction capability of CATHARE2 V1. 5 for strong and two-phase flow process should be improved further in future.
