摘要
采用管内汽液均相流模型，对竖直套管内的自然对流沸腾最大热通量（ＣＨＦ）进行理论解析并提出了简化的理论计算公式．理论公式与各类实验公式比较指出了这些公式的共同缺陷和相互间不能统一的原因．理论式和本实验及其他文献的套管，长方形通道的最大热通量实验数据进行了比较，在流路狭长的情况时两者相当吻合．
An analytical and experimental study has been made of the critical heat flux (CHF) of natural convective boiling on uniformly heated inner tubes in Vertical annular tubes submerged in staurated liquids. Based on the analysis a mixed flow model and a generalized appoximate formula are presented. It has discovered common faults of various experimental collections and agreed well with the CHF data of annular tubes and rectangular channels in water and other liquids.
