Abstract
In this study, the effects of spacer and variation of spacer height in reverse electrodialysis (RED) on the seawater and ion transport were investigated. A three-dimensional computational fluid dynamics (CFD) simulation for a hexagonal spacer was constructed. The results showed that the swirl in the channel and ion transport rate to the membrane were enhanced at higher Reynolds number, on the other hand, pressure difference between the inlet and outlet was increased. Moreover thicker spacer increased Power number and Sherwood number.
