摘要

在不同几何结构的热虹吸沸腾装置中对高Pr准数液体的流动沸腾传热进行实验研究.实验介质为乙醇、丙酮、异丁醇.Pr准数从3.81变化到26.3.将实验结果与文献数据进行比较.从机理上分析Pr 准数对两相流传热的影响

并探讨两相流因子F_(tp)的几个关联式的适用范围.

Abstract

Boiling heat transfer of flowing high Prandtl number fluids was studied experimentally in different types oi thermosyphon boiling device with various geometrical dimensions. The working media were ethanol

acetone and iso-butanol. The range oi Prandtl number was from 3.81 to 26.3. Experimental results were compared with predicted values calculated by different correlations from literature. The influence ot Prandtl number on two-phase flow heat transfer was in terms oi its mechanism. The correlations of two-phase flow factor

Ftp were examined and discussed.
