The diffusion of water vapor from semi-infinite flat porous plates has been studied by numerical analysis and experiments. The flow regarded as binary mixtures of vapor and dry air was assumed to be steady, two-dimensional and Boussinesq incompressible. Due to the temperature and the concentration differences between the pores and the ambient air, mass is transported by convection and diffusion. From the numerical and measured results, influences of the pore sizes and the spacing on the evaporation rates and the stream were discussed. Application of the results from plant leaves is demonstrated.
