Abstract

Abstract

The effect of heat flux,inlet sub-cooling and mass flow rate on bubble departure diameters was investigated in narrow rectangular channel using water as the working fluids.The experiment was done at pressure of about 0.16 MPa.The mass flow rate were between 300 and 700 kg/（m².s）;heat flux were between 27.6 and 228.3 kw/m²;and inlet sub-cooling were between 20 and 40℃.The bubble departure diameter was found not significantly affected by changes in heat flux and inlet sub-cooling while decreased for increasing mass flow rate.
