The Microfluidics Module brings easy-to-use tools for the study microfluidics devices and rarefied gas flow. Important applications include simulations of lab-on-chip devices, digital microfluidics. electromagnetic and magnetokinetic devices, inkjets and vacuum systems. In addition to enhances interfaces for single phase flow, Microfluidics Module user will have dedicated interfaces for two-phase flow using the level set, phase field and moving mesh methods. Each of these interfaces includes surface tension forces, capillary forces and Marangoni effects.
COMSOL's general purpose multiphysics features makes it easy to set up coupled electrokinetic and magneto-dynamic simulations including electrophoresis, magneto-phoresis, di-electrophoresis, electro-osmosis and electro-wetting. The chemical diffusion and reactions for dilute species interfaces included in the Module enable the simulation of processes occurring in the lab-on-chip devices. For simulation rarefied gas flows, you can use the specialized boundary conditions that activate flow simulation in the slip flow regime.
A new free molecular flow interface using the fast angular coefficient method allows for simulations where the molecular mean free path is much longer than the geometric dimensions. Combined with COMSOL's LiveLink interfaces for industry-standard CAD packages, this tool is invaluable for a vacuum system design, allowing quick parameter studies of chamber geometries and pump configurations.
