Multifaceted Convergence Study for Evaluating Gas Diffusion Parameters of Polymeric Membranes
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'In this paper, gas transport properties of PTFE (polytetrafluorethylene) polymeric membranes are studied. We focused our work on three methods based on, Darcy’s pore flow model, Fick’s diffusion and numerical analysis. Effective diffusion coefficients obtained by Darcy’s and Fick’s laws are compared. In numerical analysis, simplified computational fluid dynamics model was created using virtual porous mediumconcept. Virtual porous media is generated by adding a momentum sink term in the governing equations of fluid flow. Diffusion process described by Darcy’s method is performed using transfer of clean air through the membrane under inducedpressure gradients. Fick’s diffusion parameters are obtained based on trace compound (C3H8O) transport through the membrane under induced concentration gradients. Relatively high inertial permeabilit' .
