The Development of Heat Transfer Correlations for Evaporative Micro/Mini-channels
Existing databases and correlations in literature on the micro/mini-channel two phase flow heat transfer are reviewed in this paper.From this review,it is found that none of the existing correlations can cover the wide ranges of working fluids,operational conditions and channel dimensions.In addition,the importance of the Bond number,which relates the nominal bubble dimension or capillary parameter with the channel size,is revealed in this paper.Using the Bond number,modified correlations of heat transfer are established,which improve the prediction of the existing data over wide ranges.
