微小通道内流动沸腾换热的预测新模型
A new model for flow boiling heat transfer in mini-channels
摘要
Abstract
In order to get a method for predicting the flow boiling heat transfer in mini-channels, 2924 experimental data of flow boiling in mini-channels from 9 literatures were analyzed. As the tube diameter decreases,the surface tension rather than the buoyancy affects the two phase flow and heat transfer. The enhancement factor of convective evaporation and suppression factor of nucleate boiling of Chen-type correlation were optimized. The non-dimensional number vapor Weber number,two-phase Reynolds number,boiling number and confinement number were used to express the effects of surface tension,diameter,flow conditions and heat flux. A new model was presented to predict the heat transfer coefficient of pre-dryout in mini-channels. A mean absolute deviation of 19.0%was achieved with this new correlation.关键词
