The Effect of Radiation on Film Boiling Heat Transfer : 2nd Report, Horizontal Cylinder and Sphere Perpendicular to Upward Vertical Flow

Abstract

The effect of radiation on forced convective film boiling heat transfer from a horizontal cylinder and sphere to a subcooled liquid is analyzed by means of the integral method of boundary-layer. Numerical solutions are determined for water under the atmospheric pressure. The effect of radiation on the location of separation and heat transfer is discussed using a new parameter for radiative contribution, and the method proposed by Bromley et al. to estimate the radiation effect on total heat transfer for a horizontal cylinder is also examined.
