一般注記In this thesis 3D modelling of flow through spacer filled narrow channels is carried out using CFD package ANSYS CFX to investigate the impact of feed spacer filament on shear stress exerted on membrane surfaces and pressure drop, which two kinds of feed spacers were designed to improve flow pattern. To lower the obstacle effect from the feed spacer in the SWM feed channel, the support from the high porosity of the pillar-like with a small filament diameter was indispensable. The pillar-like feed spacer was introduced as a new template to manipulate energy consumption. To achieve enhanced mixing, the arc-like spacer was designed as the transversal filament from the upper membrane to the lower membrane. Reduction of the shadow zone behind the transversal filament was realized with the arched filament and the potential for mixing reached to the close vicinity of the filament.
