Abstract: Abstract:The study researched into a simple theoretical model for turbulent film boiling heat transfer on an ellipsoid with influence of surface tension. It begins from assuming an isothermal ellipsoid immersed in the stagnant saturated liquid. The effects of non-linear thermal conductivity, absolute viscosity, and the eddy diffusivity in the vapor film are all included in this paper. The results show, for higher eccentricity values, the eccentricity and the surface tension have some slight influence on the mean Nusselt. However, for lower eccentricity values, the influence of eccentricity and surface tension effects on the mean Nusselt can almost be neglected. Finally, a comparison between the results of the present study and those reported in previous theoretical and experimental studies is provided. And the results were found in a good agreement with the previous data.
