Recently, computational fluid dynamics (CFD) models of flows in membrane channels have been proposed and validated against published simplified models available in the literature. In this paper, experimental and numerical analysis is performed for a reverse osmosis (RO) module and results compared in order to provide further validation of the model from a practical prospective. Our results show that,...
Dynamic responses of a high-pressure (80 bar) reverse osmosis (RO) membrane system to pulse disturbances in pressure, concentration and velocity are investigated. Responses are calculated using computational fluid dynamics (CFD) and are used to develop transfer function models using system identification methods. The response of the flux to pressure changes is described by a 3-pole/3-zero model for...
