A numerical simulation based on finite differences methods has been developped to investigate the mechanism of turbulent heat and mass transfer during water evaporation inside an horisontal rectangular channel composed of two asymmetrically heated horisontal plates. The flowing gas is a mixture of dry air and water vapor. A low Reynolds number k-ε turbulence model is used. Comparisons with previous available numerical and experimental data showed that agreement is possible. The effects of different state variables as inlet temperature To, water-vapor concentration Cvo, gas pressure Pgo on different profiles are carried out and analysed.
