摘要

为了预测低温流体膜态池沸腾换热特性

研究了文献中涉及低温流体膜态池沸腾换热的实验数据

并根据加热面结构对数据进行了分类整理。以此为基础

与3种典型膜态沸腾换热模型(Bormley模型、Frederking模型和Breen & Westwater模型)的预测结果进行了对比分析

探讨了现有模型在预测不同结构加热面低温流体沸腾换热时的适用性与精度

实现了低温流体膜态沸腾换热的准确预测。研究发现

对于低温系统预冷过程

在分析膜态沸腾传热时可不考虑辐射热的影响

但必须考虑加热面结构的影响。对于水平管与球形加热面

可分别选用Bromley公式与Frederking公式预测沸腾传热系数; 对于平板与丝状结构表面

分别修正了Frederking公式与Breen & Westwater公式

修正后两模型预测误差均小于15%。研究内容为低温换热系统的设计及运行提供了可靠的理论支持。

Abstract

To predict the heat transfer characteristics of cryogenic fluid film pool boiling

the experimental data concerning film pool boiling of cryogenic fluid are summarized and classified according to heater geometries. Then three typical film boiling heat transfer correlations

which include Bormley model

Frederking model and Breen & Westwater model

are validated

and their applicability and predictive accuracy in analyzing the film boiling heat transfer on different heater geometries are comparatively discussed. Following the validation study and correlation modification

a series of correlations for the heaters with different geometries are obtained to accomplish accurate prediction of the heat transfer characteristics of cryogenic fluid film pool boiling. It is found that in the precooling process of cryogenic system

the radiation heat transfer can be ignored due to its tiny proportion to the total heat transfer

while the geometry effect ought to be taken into consideration; for the heat transfer cylinder tube and sphere heaters

Bromley's and Frederking's correlations are suggested. For the plate and wire heaters

it is necessary to modify Frederking's and Breen & Westwater's correlations in terms of experimental data

and the deviations from the modified correlations are lower than 15%.
