Laminar Film Boiling Heat Transfer on a Horizontal Cylinder Submerged in an Upward Crossflow of Saturated Liquids

摘要

An analysis was made of the steady-state, forced convection film boiling heat transfer on an isothermal horizontal cylinder submerged in an upward crossflow of saturated liquids in the gravitational field. The boundary-layer equations of momentum and of energy for the laminar vapor film, including both the inertia force in the former and the convection term in the latter, were solved using an integral method. The analytical solution was obtained for the integrated boundary-layer equations. A theoretical correlating equation for the heat transfer rate, which was derived from the solution, agreed very well with the experimental data of ethanol by Bromley et al. The correlating equation and its approximate expression were tentatively recommended because of a scarcity of experimental data.
