Abstract

Abstract

To understand the onset of bubble sliding（OBS） in sub-cooled boiling flow in a rectangular channel,a visualization study has been conducted using a high-speed digital camera system.The results show the OBS distribution in the heating plate is with the obvious parabola-shape,and the mass velocity,the heat flux and the pressure have greater effect on the distance of OBS.
