摘要

The characteristics of the evaporative heat transfer in microtubes were investigated with three circular tubes with inner diameters of 244, 430, and 792 μm, respectively. The interrelation between the heat flux and the mass flux about the heat transfer coefficients was expressed by the boiling number, which was considered to be a very important parameter to predict the trend of the heat transfer coefficients in microtubes versus the quality. A new correlation for the evaporative heat transfer coefficients in microtubes was developed by considering the following factors; the laminar flow heat transfer coefficient of liquid-phase flow, the enhancement factor of the convective heat transfer, and the nucleate boiling correction factor. The correlation developed in this study predicts the experimental heat transfer coefficients within an absolute average deviation of 8.4%.
