抄録
The boundary layer equations for free-convection laminar film condensation of pure vapors of water, ethanol and propane on a vertical surface are numerically solved for the cases of constant properties, variable viscosity and variable relevant physical properties. The conclusions are as follows: (1) The ratio of the heat flux at the vapor-liquid interface to that at the cooling surface is expressed by [numerical formula] (2) The correction for Nusselt's equation due to the thermal convection effect is roughly estimated by [numerical formula] (3) The dimensionless reference temperature r_T derived from Fujii's aproximate analysis has been confirmed by the numerical results for the case of variable viscosity. (4) The Nusselt's equation evaluated by the physical properties at r_T=1/4 predicts heat flux at the cooling surface within an error of two per cent.
