Local measurements of vapor phase heat and mass fluxes and of heat fluxes through condensate liquid film were made for the forced convection film condensation of steam, methanel, benzene and carbon tetrachloride vapors on a small vertical flat plate in the presence of air with air mass fraction of 0.027-0.787. Measured vapor phase fluxes are compared with the theoretical value by laminar boundary layer theory over a flat plate with Blasius-type similarity transformation. A new method which enables one to evaluate the surface temperature of the condensate liquid film and the wall heat fluxes in the presence of noncondensable gas is proposed. The effect of vapor shear stress on the rate of heat transfer through condensate liquid film flowing cocurrently with vapor is also discussed.
