CFD modeling of the H2/N2 separation with a nickel/α-alumina microporous membrane

The computational fluid dynamics (CFD) approach is used. The simulation is based on the numerical solution of the three-dimensional (3D) Navier-Stokes equations coupled with the species governing equations on the three dimensional domain representing quite closely the selected module geometry. The permeability fluxes are calculated at different temperature and transmembrane pressures and compared with the experimental data. The simulation predictions show fairly good agreement with the measured permeation data.
