Computational Fluid Dynamics for Design of Gas Separation Membrane Module

Abstract

Computational fluid dynamics (CFD) calculation was successfully demonstrated for H₂/CO permeation through the membranes. CFD calculation was performed using the tube geometry model with the same conditions as the previously reported experiment. The concentration polarization observed in CFD simulation compared well with that reported experimentally. This suggests the CFD simulator can be used to design a membrane module involving prediction of selectivity and cut with consideration of concentration of polarization.
