Abstract
The critical heat fluxes on inclined plates were investigated analytically by using macrolayer model and Kelvin-Helmholtz instability. In the present model, most dangerous wavelength and propagative velocity in Kelvin-Helmholtz instability were calculated to determine the length and the velocity of a coalesced bubble on a heating surface at CHF. The time covered over the heater was estimated as the calculated value with the length divided by the velocity. The predictions of the model agreed well with previous experimental data for CHF on inclined plates with 30 to 180 degree in orientation. The present model was developed to the CHF on a hemisphere surface.
