Computational micro fluid dynamics using COMSOL multiphysics for sample delivery in sensing domain

Engineering of fluid flow with within various structure for different application is a scientific quest and Microfluidic devices present a powerful platform for working with living cells and other medical application. The length and volume scales of these devices in miniaturize system make it possible to perform detailed analyses with several advantages. However, the COMSOM Multiphysics approach was not addressed a sufficiently. This paper reports, COMSOL multi physics based model for fluid flow within a Polydimethylsiloxane (PDMS) polymer. The trend predicted by the new model agrees with experimental extrusion results observed. The proposed method allows further extension to study of the structural property of fluid in the COMSOL environment for possible interaction with sensor transducer.
