摘要

This paper presents results of numerical investigation of film boiling heat transfer and flow structure by means of local-homogeneous-slip model. Performance of this model is examined against experimental data of Nishio and Ohtake, obtained for natural-convection film boiling of freon R113 around horizontal cylinders. The calculation results demonstrate the capability of the model to describe both the surface-average and local distribution of heat transfer coefficient under film boiling conditions. In particular, convective waves on liquid-vapor interface were predicted. Sensitivity analyses revealed a slight dependence of the predicted results upon the definition of therm ophysical properties in the two-phase region. However, the model is found to be sensitive to slip factor S.
