摘要

以去离子水为实验介质，对截面为3 mm×43 mm的三面加热窄矩形通道内饱和沸腾（FDB）起始点进行了实验研究。分析了部分热工参数对饱和沸腾起始点的影响，对三面加热窄矩形通道内饱和沸腾起始点的数据进行非线性回归分析，得到适用于三面加热窄矩形通道饱和沸腾起始点热通量的经验关系式。结果表明：新拟合得到的关系式能较准确地预测三面加热窄矩形通道内饱和沸腾起始点的热通量，其预测值的相对误差为15.17%。将新关系式计算结果与现有实验数据进行比较，源于单面加热窄矩形通道的实验数据与新关系式符合程度较好，表明新关系式可适用于单面加热窄矩形通道。

Abstract

The deionized water was used as the experimental medium

and the fully developed boiling (FDB) starting point of the three-sided heated narrow rectangular channel with a section of 3 mm×43 mm was studied. The influence of some thermal parameters on FDB starting point is analyzed. Empirical correlation of FDB's heat flux suitable for the three-side heating narrow rectangular channel was obtained by nonlinear regression analysis for experimental data of FDB starting location. The results show that the new empirical correlation can accurately predict heat flux of FDB in the three-side heating narrow rectangular channel. The relative error of predicting value is 15.17%. Besides

the simulation results of new empirical correlation are compared with some existing experimental data. The experimental data obtained from one-side heating narrow rectangular channel are in fairly agreement with new empirical correlation. This shows that new empirical correlation is well suited for one-side heating narrow rectangular channel.
