Abstract

Heat and mass transfer between a horizontal moving water film and air flowing over the film is theoretically investigated. In the present theoretical model, the flow of air over the moving water film is assumed to be laminar and steady in Cartesian coordinates. The governing equations are the continuity, momentum, energy and concentration equations. These governing equations set of equations to determine the distribution of the dimensionless velocity, temperature are in a dimensionless form. By introducing new proper independent and dependent variables, the governing equations are transformed to a set of dimensionless differential equations. A computer program in FORTRAN language is developed to solve this and concentration. Also, local values of Nusselt and Sherwood numbers for different values of Reynolds number are calculated. 
Comparison between the obtained results and the previous works show good agreement. The results show that, Nusselt and Sherwood numbers increase with increasing Reynolds number.
