    Abstract: The performances of DCMD and VMD in seawater desalination were studied in this work. The operating parameters included temperature difference, feed flow rate, and module inclination angle. The various channel design in the feed side was also investigated. The experimental results show that increasing the temperature difference will increase the distillate flux, but also heighten the polarization phenomena. The enhancement in distillate flux by increasing the feed flow was higher in DCMD operation than that in the VMD system. In DCMD system, the distillate flux increased as the module inclination angle increased, and reached a maximum at about 45°. Aeration in DCMD system also enhanced the flux. It is notable that the convex design in the feed channel could effectively reduce the polarization phenomena, and thus increase the distillate flux.
