Abstract

In this paper, we have developed a three dimensional numerical method based on 3D-VOSET+IDEAL methods to study bubble dynamics and heat transfer during a growing and departing bubble on a horizontal surface. The three dimensional solid wall is also coupled into the solver to study the response of a heated solid surface during nucleate boiling. In the method, the interface is tracked by the three dimensional coupled interface capturing VOSET method. Beside, 3D-IDEAL algorithm is adopted to couple the velocity and pressure field. From the numerical simulation, good agreement is observed in prediction of bubble shape of saturated water at departure with experimental data. The departure diameter of saturated FC-72 predicted by the proposed method matches very well with Phan's correlation. A comprehensive and richly detailed analysis on temperature distributions near the bubble and inside the solid wall is carried out.
