Summary

A numerical analysis is carried out to study bubble growth in saturated heterogeneous boiling. The bubble growth is determined by considering the simultaneous energy transfer among the vapour bubble, liquid microlayer, and heater. The predicted bubble growth rate compares very well with the reported experimental data over a wide range of conditions. Four dimensionless parameters governing the bubble growth have been identified: Jacob number, Fourier number, thermal conductivity ratio and thermal diffusivity ratio of the liquid to solid. A systematic investigation on the dependence of the bubble growth rate and the thermal fields of the microlayer and heater on these dimensionless parameters is presented.
