Frequently asked questions

Q1. What are the contributions mentioned in the paper "Fluid dynamics of spacer filled rectangular and curvilinear channels" ?

In this work fluid dynamics of rectangular channels similar to membrane modules and containing different spacers was simulated using a three-dimensional computational fluid dynamics ( CFD ) model. In addition to predicting the pressure drop, the simulated results provided significant insight into fluid dynamics of spacer filled channels. The approach and results presented in this work will have significant implications for identifying improved spacers with higher propensities to reduce fouling in membrane modules.
