Abstract: Abstract: The theoretical study investigates turbulent film boiling on a sphere immersed in the stagnant liquid. It begins by assuming the surface temperature of the sphere is isothermal. The result shows that the boiling heat transfer under the turbulent vapour shows that both the temperature and the velocity present a non-linear distribution. Besides, the increase of the thermal radiation, wall temperature and buoyancy effects can enhance the heat transfer efficiency. Furthermore, a comparison between the results of the present study and those reported in a previous theoretical study of laminar film boiling is provided. It is found that turbulent film boiling with higher Rayleigh number will have higher Nusselt number.
