摘要: The mechanism of the critical heat flux (CHF) where departure from nucleate boiling (DNB)-type transition takes place has not been fully elucidated. In this paper, we examine trigger CHF for saturated and subcooled pool on vertical inclined surfaces based measurements liquid-vapor behaviors near heating by using a conductance probe. angle inclination was varied 90° (vertical) to 170° (facing almost horizontally downwards). probe signals void fraction distributions showed that liquid layer remains beneath vapor masses moving upward along surface at high fluxes CHF. thickness determined location corresponding disappeared. formed increased with increasing degree subcooling, which may be cause increases in subco...
