Dynamics of the wall thermal boundary layer at the initial stage of the nucleate boiling

... boiling, we used a numerical model implemented in the COMSOL multiphysics software. The experimental data on bubbles dynamics was compared to the numerical calculation of the temperature, and the relationship between the temperature growth rate, the bubble departure diameter and the Jacob number was established. The outcome results demonstrated that the non-transient heat influences the departure diameter and we need to employ the modified Jacob number to build predictive models. © Published under ...
