The Influence Of Surface Radiation On Laminar Forced-Convection Film Boiling

Keywords

film boiling; forced convection; radiation

Abstract

A new approach to address the effect of surface radiation on a laminar film boiling flow over a horizontal flat plate is suggested. Previously developed approximate expressions of the thermal boundary-layer thickness and the wall shear stress of a moving surface in a flowing liquid are used to circumvent the complicated simultaneous solution of the vapor and liquid flow. Approximate closed-form expressions to predict the wall heat transfer and skin friction are obtained. For a water-steam system at atmospheric pressure within the wall temperature range considered (Tw<800°C), the surface radiation contribution is negligible in the theoretical wall heat transfer predictions during subcooled T∞=20°C forced-convection film boiling. © 1991.
