The natural convection heat transfer characte-fistics of a vertical array composed of three horizontal tubes are presented, including the relations between the wall temperature, Nussett number of various tubes, the average Nusselt number of the array and s/D. From the above relations, we showed that the tube wall temperature had a transition point when the s/D of the array was increased from 2 to 4. At this point, the average Nusseit number of the array surpassed the Nusselt number of a single tube, the transition...

The natural convection heat transfer characte-fistics of a vertical array composed of three horizontal tubes are presented, including the relations between the wall temperature, Nussett number of various tubes, the average Nusselt number of the array and s/D. From the above relations, we showed that the tube wall temperature had a transition point when the s/D of the array was increased from 2 to 4. At this point, the average Nusseit number of the array surpassed the Nusselt number of a single tube, the transition occured between Gr_H (H/D)~(1.25)=7×10~7~2.5×10~8. This value can be used to select the economical s/D. When the s/D increased from 10 to 20, the wall temperature increased again and the average Nusselt number decreased.

本文给出了三根横管组成的垂直管排的自然对流换热特征,包括各排的管壁温度、努赛脱数以及管排平均努赛脱数三者与S/D之间的关系。由这些关系可以得出下述结论;当s/D由2增至4时,管壁温度发生转折,平均努赛脱数开始超过单管的努赛脱数,转折点发生在GrH(H/D)~(1.25)等于7×10~7~2.5×10~8之间,此值可用来选择经济的S/D值。当s/D由10增至20时,管壁温度回升,平均努塞特数下降。

This paper discusses the rate at which the frost layer thickens on a cold surface under forced convection, and gives the equations for the parameters related to frost formation. The laws of heat and mass transfer in the sublimation frost formation are analysed. The rate equations for frost fromation are obtained when the fact is taken into consideration that the frost fromation is influenced by the density of the frost laver and the ambient temperature.The equation for finding initial frost density is achieved...

This paper discusses the rate at which the frost layer thickens on a cold surface under forced convection, and gives the equations for the parameters related to frost formation. The laws of heat and mass transfer in the sublimation frost formation are analysed. The rate equations for frost fromation are obtained when the fact is taken into consideration that the frost fromation is influenced by the density of the frost laver and the ambient temperature.The equation for finding initial frost density is achieved on the assumption that the temperature in the first frost layers is of linear distribution.A program is made for calculating the rate equations of the frost formation and the equation for selecting initial values. The calculations on TRS-80 Microcomputer exhibit good agreement with Yonko and Sepsy [1] experimental data.

本文对于强迫对流条件下水平壁面上水蒸汽凝华结霜问题提出了有关参数的表达式,分析论述了凝华结霜过程中基本的传热传质规律。在考虑霜层密度和环境温度对霜层结构产生影响的情况下给出了凝华结霜速率方程,同时在假定初始霜层中温度是线性分布的条件下给出了确定霜密度初值的方程组。本文对凝华结霜增长速率方程组和选择初值的方程组进行数值计算的程序设计,在TRS—80计算机上对不同条件下结霜速率进行了数值计算,其结果基本符合Yorko和Sepsy的实验数值[1]。
