| Abstract: | The characteristics of membrane distillation were analyzed.The progress in studies on heat and mass transfer mechanism in direct contact membrane distillation was discussed,including the development of models,temperature polarization, concentration polarization, the determination of heat transfer coefficient and the influence of membrane physical properties and fluid dynamics. And the valuable researches on transfer mechanism in the process were pointed out. |
