Investigation of bubble departure diameter in horizontal and vertical subcooled flow boiling

•The force balance approach and correlation approach are conducted to predict bubble departure diameter.•A new semi-empirical correlation for bubble departure diameter is proposed in this paper.•The effects of dimensionless parameters on bubble departure diameters are analyzed. According to the forc...
