摘要
介绍了2种适用于发动机冷却水传热计算的单相流沸腾模型Chen模型和BDL模型,通过对鼻梁区简化模型的数值模拟计算和实验结果对比分析,得到"BDL沸腾传热模型+SST湍流模型"的数学模型,计算误差更小。
This article describes two single-phase flow boiling model for heat transfer calculation in ICE,which are CHEN model and BDL model.Based on the origin model,comparison has been made between numerical calculation and experimental comparison.Smaller calculation error is achieved when ＂BDL＋SST＂ model is used.
