Abstract
Based on the equation that the heat conduction from the bubble underlying layer is balanced with the heat convection of bubble cooling and the latent heat of evaporation, with the help of zhao model a new bubble growth model for the forced convective subcooled boiling in the engine cooling system is developed with the consideration of the thermal boundary layer impact on the bubble growth. And an experiment is designed to verify the theoretical model. Then the Klausner model for predicting the bubble lift-off diameters is amended with the built bubble growth model. In addition, the bubble lift-off diameters at the different velocity are predicted, which is verified with the experimental data.
