Abstract

By applying a linear Rayleigh-Taylor stability analysis to a liquid-vapor interface under the influence of adverse gravity field and with appreciable interfacial heat and mass transfer (vaporization), a new dispersion relationship has been derived that predicts the linear stability with respect to disturbances of any wavenumber, for a critical value of basic state heat flux. The inclusion of phase change in the basic state and thus the effect of vaporrecoil is the distinctive feature of this analysis that makes it a more realistic hydrodynamic model for film boiling than the earlier formulations which assumed no appreciable vaporization in the basic or equilibrium state.
