Fig. 9: SLIPS performance improvement at scale.

From: Slippery liquid infused porous surface (SLIPS) condensers for high efficiency air gap membrane distillation

Fig. 9

Energy efficiency (GOR) and permeate production for slippery liquid infused porous surface (SLIPS) -adjusted models and a filmwise condensing regime are shown at various salinities. Efficiency curves are plotted at the optimal gap size at each salinity for SLIPS. For filmwise condensation, the efficiency frontiers at 5 and 35 \(\frac{g}{{kg}}\) salinities have been plotted at the gap sizes that prevent flooding (0.1 and 0.14 mm respectively) whereas for other salinities gap size is identical to SLIPS. Module length is varied from 0.5 to 30 m to properly capture the GOR value peaks for the considered salinity range of 5–105 \(\frac{g}{{kg}}\). The shaded areas indicate the improvements made through SLIPS.
