Experimental approaches were taken to examine heat and mass transfer in evaporation of the methanol–2-propanol and the methanol–water systems into dry air by a cocurrent vertical flat-plate wetted-wall column over wide ranges of gas and liquid flow rates and liquid concentrations.
The observed gas-phase sensible heat fluxes are compared with a theoretical analysis of heat transfer in a laminar boundary layer under high mass flux with finite tangential surface velocity. The effect of evaporative mass injection, tangential surface velocity and interactions between diffusion fluxes on the observed gas-phase diffusion fluxes are discussed. The observed diffusion fluxes are compared with a theoretical analysis of ternary mass transfer in a laminar boundary layer by taking into account the effect of interactions between diffusion fluxes under high mass flux with finite tangential surface velocity.
