摘要

摘要: 考虑到不同流道结构参数对流动沸腾临界热流密度（CHF）的影响，提出一描述流道结构参数影响的广义影响因子D_n，基于相似理论和量纲分析理论导出了含有参数n的13个相似准则数，并与Ahmad的推导结论进行了比较。对比结果显示，Ahmad的推导结论是本文结论n=1时的特殊情形，也可认为本文定义了一新的能够集中反映复杂流道型式对CHF发生机理影响的等效特征尺寸D_e。

Abstract: A generalized factor D_n was introduced to the fluid to fluid modeling to take into account the effect of flow channel geometrical parameters on critical heat flux (CHF). Thirteen similarity dimensionless products were derived based on the dimensional analysis and similarity theory and compared with those derived by Ahmad. It is found that Ahmad’s results are the special situation of the paper’s when n is equal to 1, and a new equivalent characteristic size D_e was developed, which could reflect the effects of complex flow channels on the occurrence of CHF.
