一、引言 六十年代初,文献[1,2]报道过两侧热流密度相等时外侧传热系数的实验结果,它们都比理论计算值高得多。等热流密度时内侧传热系数及不等热流密度时两侧传热系数的实验结果至今未见报道。 本文介绍热流密度相等和不相等时两侧的传热系数,得到的半经验公式与Dwyer的理论式 I. INTRODUCTION In the early 1960s, the literature [1,2] reported the experimental results of the outside heat transfer coefficient when the heat flux at both sides were equal, which were much higher than the theoretical ones. When the heat flux density and other heat transfer coefficient and heat flux density on both sides of the heat transfer coefficient of the experimental results have not been reported. In this paper, the heat transfer coefficients on both sides of equal and unequal heat flux are introduced, and the semi-empirical formula and Dwyer’s theoretical formula
