摘要

In this study, a mathematical model was developed for falling film evaporation. Laplace transform is applied to the partial differential equations for the combined heat and mass transfer problem in laminar falling films with uniform film thickness. The model was developed in cylindrical coordinate while most of the previous works ignored the reality flow pattern of the falling film. The main factors influencing the heat and mass transfer performance were calculated and analyzed. The results indicated the relative rates at which the temperature and concentration profiles develop and show the variation of the interface heat and mass fluxes with normalized length.
