用灰色系统理论预测环形通道内液钠的临界热流密度
Prediction of Sodium Critical Heat Flux(CHF) in Annular Channel Using Grey Systems Theory
-
摘要: 用灰色系统理论对在两台液钠沸腾实验回路上测得的实验数据进行了钠沸腾临界热流密度(CHF)值影响因素的灰色相关分析, 并用GM(1,1)模型对CHF进行预测, 选用GM (1,h)模型对CHF进行了建模。计算及预测结果与实验值符合较好。Abstract: Using grey systems theory and experimental data obtained from sodium boiling test loop in China, the grey mutual analysis of some parameters influencing sodium CHF is carried out, and the CHF values are predicted by GM(1,1) model. The GM(1, h ) model is established for CHF prediction, and the predicted CHF values are good agreement with the experimental data.
