Numerical analysis of the evaporation of water flowing across an inclined plate in a laminar and turbulent moist-air current

The authors have proposed an appropriate model based on the liquid film tra nsfer equations which are one-dimensional, partially two-dimensional and tw o-dimensional. They have compared their results with those of other work; a nd studied the influence of the liquid mass flow rate and the inclined angl e. They have shown that the interfacial heat transfer is dominated by the l atent heat transfer; the contribution of the sensible heat is only importan t in the turbulent region where the interfacial temperature and the evapora ting mass flux are practically constant and the thickness of the liquid fil m is uniform. For the adiabatic plate, the liquid mass flow rate and the in clined angle have no influence on the transfers. For the isothermal or the heated plate, the liquid mass flow rate essentially influences the turbulen t region by reducing the interfacial temperature and the heat and mass tran sfer coefficients. However, the inclination angle affects mainly the lamina r region by increasing the interfacial velocity, reducing the film thicknes s and has little effects on the transfer coefficients.
