Modeling and simulation of a membrane module
MetadataShow full item record
This work presents a way of simulating the operation of an anion exchangemembrane module. A CFD simulation of this module was made in OpenFOAMsoftware. The membrane module contains an ion exchange membrane and isused for separation of organic acids. It consists of an dilute and a concentratecompartments, separated by the mentioned membrane. In the model, onlyacetic acid was taken into account. A movement of acetic acid ions from thedilute compartment, trough the membrane and to the concentrate compartmentunder the eect of an electric eld was assumed. Electrochemical reactionswere not taken into account. First, a mesh describing the membrane modulegeometry is build. Two meshes have been built, a simplied one and a moredetailed one. Then, pre-process utilities that have been used in this work areexplained followed by boundary conditions. After that, the solver of this modelis explained along with post-processing tools. The results present a simple,functioning membrane module model. Lastly, a number of future developmentpossibilities are discussed.
