Since the Microfluidics Module leverages COMSOL Multiphysics, you can couple your modeling of these effects with thermal and electromagnetic effects. At the microscale, flow is usually highly ordered laminar flow, and the lack of turbulence makes diffusion the primary mechanism for mixing. It is used to simulate chemical species transport through diffusion, convection (when coupled to fluid flow), and migration in electric fields for mixtures where one component a solvent is present in excess (90 mol% or greater). The manipulation of contact angles by the electrowetting phenomena is also easy in microscale devices. The Reynolds number (Re) that characterizes the ratio of these two forces is typically low, so the flow is usually laminar. To model a microfluidic device, you begin by defining the geometry in the software by importing a CAD file or via the geometry modeling tools that are built into COMSOL Multiphysics. are standardized to provide the same functions and operations across multiple platforms. At the microscale level, however, neither of these approaches is While diffusional mixing of small molecules (and therefore of rapidly diffusing species) can occur in a At the macroscopic level, systems usually mix fluids using mechanical actuators or turbulent 3D flow.
