Abstrakt

In this paper, the bubble growth and heat transfer in a rectangular mcirochannel were studied. The coupled level set and VOF method-VOSET was used to capture the liquid-vapor interface, and the velocity and pressure fields was solved by the projection method. The effect of the contact angle and inlet liquid velocity on the bubble growth and wall heat transfer were systematically studied. It is found that the average heat flux increas with the increase of the inlet liquid velocity, while decreas with the increase of the contact angle.
