Gas Permeation Modeling through a Multilayer Hollow Fiber Composite Membrane

In this study, a time-dependent 2D axisymmetric model of a multilayer hollow fiber composite membrane for gas separation is proposed. In spite of the common multilayer membranes, which a dense layer coated on a porous support layer and subjected into the feed stream, here, the porous support is exposed to the feed gas. In this regard, the governing equations of species transport are developed f...

Membrane Structure and Permeation Property of Polymer/Liquid Crystal Composite

Tisato Kajiyama Faculty of Engineering, Kyushu University, Fligashi-ku, Fukuoka 812 A bimolecular membrane of phospholipids such as lecithin is in a state of liquid crystal capable of reversible structural modifications and its permeation property depends on such reversible change. Artificial amphiphiles with monoalkyl and dialkyl groups form multilamellar liposome composed of the bimolecular l...

Collocation method for the modeling of membrane gas permeation systems

In this work, we describe a numerical method which enables an efficient computation of membrane gas permeation processes that involve multiple membrane stages and multiple gas components. The utilized numerical approach is a collocation method equipped with a grid adaptation strategy based on a dependable error estimate of the numerical approximation. The comparison of the results provided by t...

On gas permeation in PDMS

A theoretical model of gas permeation in polydimethylsiloxane (PDMS) is conducted for two prior works involving MEMS sensors and actuators. The issue for modeling a sensor is about using PDMS slabs to replace Pyrex glass as the packaging substrate for bulk-micromachined pressure sensors. The leakage pressure due to gas permeation in PDMS reveals the time-varying behavior of exponential decay. T...
