SIMILARITY SOLUTION FOR LAMINAR-FILM BOILING OVER A MOVING ISOTHERMALSURFACE

Forced film boiling arises when a liquid flows over a highly superheat ed surface or when the surface moves through a liquid which is station ary or is itself in motion. As a result of the vapor layer separating the surface and the liquid, there is a significant reduction in the dr ag force and heat transfer. In this study, a similarity solution of th e boundary layer equations is obtained, and for a wide range of subcoo ling parameters and surface velocities, related numerical results are shown to be in excellent agreement with predictions based on an integr al method.
