Bubble departure size of multiple bubbles were investigated to explore bubble dynamic based on VOF visual simulation. By contrast, bubble departure size increased with the increasing of velocity from 0.2 m/s to 0.4 m/s and with the decreasing of subcooling degree from 10K to 3K. It was also found that there was little difference in bubble departure size corresponding to heat flux of 200 kw/m2, 300 kW/m2 and 400 kW/m2, but the magnitude of heat flux increased the number of nucleation that contributed to the increasing of bubble size due to coalescence. Finally, a fitting correlation was proposed to predict bubble departure size based on important dimensionless numbers regarding velocity, heat flux and subcooling degree, and the prediction deviation is about 5%.
