Computational study of gas separation using a hollow fiber membrane

摘要: Abstract Computational fluid dynamics simulations are conducted for binary mixture flows in a hollow fiber membrane. The membrane is modeled as functional surface, where the mass fluxes of each species will be determined based on local partial pressures, permeability, and selectivity Baseline Reynolds Stress (BSL Stress) turbulence model Brinkman–Forchheimer equations employed to study spatial structure flow inside lumen porous layer number up 400. process separating CO2 from CH4 improved by presence orifices system about 60%. degree improvement greater at higher rate. influence momentum mixing induced strongly depends permeability thickness support layer. It demonstrated here that altering placing restricting devices can used design application gas–gas separation.
