Abstract
This is the first report on our attempt to establish a theoretical model predicting the full boiling curve from nucleate to film boiling region. In the model presented here, the boiling curve is calculated based on a theoretically calculated fraction of liquid-solid contact and correlating equations for nucleate and film boiling heat transfer. The model determining the fraction of liquid-solid contact is developed based on the following three mechanisms, which have been proposed for the transient CHF : macrolayer dryout, packing of bubbles created by boiling nucleation, and packing of bubbles by spontaneous nucleation. The calculated results show that the present model can describe the outlines of full boiling curves and quantities for liquid-solid contact.
