Study of mass transfer characteristics for a hollow fiber reverse osmosis module

However, this analytical model contained the anomaly that the simulated boundary layer thickness is larger than the apparent length of the clearance among hollow fibers. Here, we propose a hollow Fiber Group Model that is consistent with the features of the hollow fiber arrangement of the practical reverse osmosis module. As a result of verifying this model, it was confirmed that the boundary layer thickness on the surface of the fiber group is smaller than the length of clearance between the fiber groups. Consequently the anomaly was broken off by this Fiber Group Model.
