Flow analysis in gas separation membrane module using porous media approach.

During the past few decades, membrane modules, mainly hollow
fiber ones, have played a major role in gas separation due to their lower en-
vironmental impact. In contrast, the number of studies employing an Eulerian
approach on the topic is relatively smaller due to the complexity of the geometry.
The high amount of compacted fibers hinders the meshing capabilities. In that
way, this study analyzes the influence of a porous media on gas flow. That builds
a foundation for a model that bypasses the complexity of geometry dealing with
the volume of fibers as a porous media with a sink term, making it possible to
produce better CFD results for this kind of operation.
