Abstract：

The physical model for thermal medium heating system of water-in-glass evacuated tube with the guiding plate is established, aiming at for simplified thermal medium heating system in solar membrane distillation. Two simulation models of solar collector system and the membrane distillation are adopted, and two coupled integration points are proposed which locates at in outlet of the united manifolds in solar collectors and inlet of heat capacity chamber in membrane distillation system, at the same time, coupled boundary conditions and solving methods on the unsteady-state flow and ideas are given. The three-dimensional unsteady state CFD model of solar energy membrane distillation system is set up, and temperature for outlet are obtained, and membrane flux and solar radiation intensity variation under non-steady-state are obtained. The results lay the foundation for optimization on further utilization of solar energy coupled with membrane distillation.
