摘要
本文从低肋管沸腾传热机理着手,综合分析了低肋管几何参数对沸腾传热的影响,导出了影响低肋管最优结构的有关准则;进行了低肋管沸腾传热试验,试验工质为蒸馏水和R—113;试验在当地大气压下进行。综合试验数据,建立了低肋管几何参数优化设计准则式。
On the basis of the mechanism of the boiling heat transfer on low finned tube, the influence of the geometric parameters of low finned tube on boiling heat transfer is synthetically analyzed and relevant criteria which affect the optimal structure of low finned tube is deduced in this paper. The boiling heat transfer experiment on low finned tube is conducted. Distilled water and R-113 are used as test fluids The experiment is performed at local atmospheric pressure. Synthesizing a large amount of experimental data, the semiempirical equations for the optimal geometric parameters of lowfinned tube are established
