Numerical simulation and theoretical study on simultaneous effects of operating parameters in vacuum membrane distillation

► This research focused on Persian Gulf water desalination via VMD. ► Simulation of the effects of operating and membrane parameters on the membrane flux. ► Little impact of feed velocity on flux, but important effect on polarization reduction. ► The more the feed temperature, the more the heat transfer coefficient impacts on flux. ► Regarding the whole effects, the optimum range of membrane thickness was determined.
