abstract = {The gas flow through porous media including that of
multiple species is frequently described by the binary
friction model (BFM) considering the binary diffusion,
Knudsen diffusion, and viscous flow. Therefore, a numerical
simulation was performed on a microporous support of an
asymmetric oxygen transport membrane. As its exact numerical
solution is complicated and not always possible, the results
of two different levels of simplification of the pressure
profiles within the porous support are compared to the exact
numerical solution. The simplification using a constant
pressure equal to the gas pressure outside the support leads
to a deviation by up to 0.45 mL·min−1·cm−2 from the
exact solution under certain operating condition. A
different simplification using a constant pressure averaged
between the outside of the support and the support/membrane
interface reduces this deviation to zero. Therefore, this is
a useful measure to reduce computational efforts when
implementing the Binary Friction Model in computational
fluid dynamics simulations.},
