Abstract
The effect of gravity on nucleate pool boiling is considered. The static and dynamic forces acting on a growing vapor bubble on a heating surface are evaluated and how their interaction causes the bubble to detach from the surface is presented. By using a force balance, an estimate of the bubble departure radius is calculated and compared with experimental measurements from literature under micro-gravity conditions. In addition, five well known theoretical correlations are used to predict the bubble departure radius and are compared for several gravitational accelerations.Keywords
