Evaporation of water/ammonia binary liquid film falling down on one plate of a vertical channel

摘要

A numerical study was conducted to investigate the coupled heat and mass transfer during the evaporation of a water/ammonia liquid film under mixed convection. This binary liquid film is falling down on one plate of a vertical channel. The wetted plate is adiabatic while the dry plate is isothermal. Parametric computations were performed to investigate the effects of the inlet parameters of the water/ammonia binary liquid film on the temperature at the liquid-gas interface and on the mixture evaporation rate.
