摘要(Abstract):

对几组混合工质强制对流沸腾换热系数计算的实验关联式进行分析比较。利用收集到的实验数据 ,在Bennett和Chen关联式与Rivera关联式的基础上进行管内强制对流沸腾传热的计算。并与Rivera的实验结果进行比较 ,得到适合氨 /水混合物沸腾换热的计算式 ,并分析影响换热系数的因素。
Several sets of correlations of calculating forced convective boiling in mixtures are compared and analyzed. Using the experimental data of the W.Rivera,the forced convective boiling heat transfer coefficients inside tube are calculated based on the correlations of Bennett and Chen,then compared with the experimental results.The appropriate correlations are given at last. Factors that affect the heat transfer coefficients are analyzed.
