Abstract

This paper presents a theoretical and numerical investigation of the effects of film cooling on the condensate layer formation on cooled flat plates. Film cooling decreases or eliminates condensation by decreasing the partial pressure of the vapor near the surfaces since injection fluid contains less or no condensible vapor. In order to study this phenomena a two dimensional boundary layer code STAN5 along with an injection and augmented mixing length model is used to calculate the heat and mass transfer Stanton numbers and skin friction coefficients over a film-cooled flat plate.
