Simulating Membrane Separation in COMSOL Multiphysics®
Länge: 40:37
In this archived webinar, originally hosted by the American Institute of Chemical Engineers (AIChE), learn how to model transport phenomena and homogeneous reactions when simulating membrane dialysis in the COMSOL Multiphysics® software. We discuss the reactions of solutes at membrane surfaces as well as their transport through membranes, built-in models for simulating membrane separation, and how to use COMSOL Multiphysics® for studying membrane dialysis.
