摘要

从12篇关于微型/微型通道文献的公开文章中，共收集了1210个新的冷凝摩擦压力梯度点（数据库）。该数据库涵盖了与低全球升温潜能值制冷剂相关的广泛热物理特性、物理尺寸、质量速度和蒸汽质量。将实验数据库与11种两相流摩擦压降预测工具进行了比较。在此基础上，徐和方开发的微型/微型通道对数据库趋势的捕捉能力最强，所有数据的平均绝对相对偏差为（36.59%）。关键词：两相流摩擦压力梯度；微型/微型通道；冷凝流；新型制冷剂；传热；收集数据库。

FRICTIONAL PRESSURE DROP DURING CONDENSING FLOW INSIDE MINI/MICRO-CHANNELS: PREDICTIVE TOOLS ASSESSMENT AND DATA TREATMENT

A total of 1210 new condensation friction pressure gradient points (database) is collected from 12 open articles on mini/micro-channels literature. The database covered a wide range of thermophysical properties associated with low-GWP refrigerants, physical dimension, mass velocity and vapor quality. A comparison of the experimental database against eleven two-phase flow frictional pressure drop prediction tools is carried out. Based on that, the mini/micro-channel developed by Xu and Fang exhibited the best ability to capture the tendency of the database with a mean absolute relative deviation of (36.59%) for all data. Keywords: Two-phase flow frictional pressure gradient; Mini/micro-channels; Condensing flow; New refrigerant fluid; Heat transfer; Collect database.
