This model is about a performance model of direct contact membrane distillation. Membrane distillation (MD) is a thermally driven separation program in which separation is enabled due to phase change. A hydrophobic membrane displays a barrier for the liquid phase, allowing the vapor phase (e.g. water vapor) to pass through the membrane's pores. The driving force of the process is given by a partial vapor pressure difference commonly triggered by a temperature difference. In DCMD, both sides of the membrane are charged with liquid- hot feed water on the evaporator side and cooled permeate on the permeate side. The condensation of the vapor passing through the membrane happens directly inside the liquid phase at the membrane boundary surface. Since the membrane is the only barrier blocking mass transport, relatively high surface-related permeate flows can be achieved with DCMD. The user has to assign the system geometry to get all performance aspects such as productivity, number of pores, efficiency, flux, mass transfer, GOR, etc...
 
**MatLab-SimuLink should be used to run the model.
