For example, write "COMSOL Multiphysics" and not "CMP". We validated the numerical model used in this work for the reported device design by developing a simple y-channel microfluidic device with square, The saw-tooth electrode profile appears to be an improvement over existing designs in that the sharp corners reduced the required horizontal distance needed for separation to occur and contributed to an asymmetric DEP electric field. To simulate mixing two different fluids with COMSOL Multiphysics software, you can follow these general steps: Set up a 3D geometry of the mixing device or Our validation model is based on CAD geometry of the wing provided by the Langley Research Center at NASA, which we imported into COMSOL Multiphysics using the CAD Import Module. Sajeesh, P.; Sen, A.L. The next section discusses the laminar microfluid flow modelling.
