Microfluidics Module

The latest addition to the COMSOL Multiphysics simulation software, the Microfluidics module provides easy-to-use tools for studying microfluidic devices and rarefied-gas flows. The module is designed for such application as lab-on-a-chip devices, digital microfluidics, biosensors, electrokinetic and magnetokinetic devices, inkjet technology, and vacuum system design. It includes interfaces for single-phase flow, which can be used to simulate such applications as compressible-gas flows at low pressures, non-Newtonian flows, and laminar and creeping flows that typically occur in lab-on–a-chip systems. It has modeling interfaces for executing two-phase flow simulations using the level set, phase field, and moving mesh methods, as well as a variety of important fluid-interface effects, such as surface tension forces, capillary forces, and Marangoni effects. The module can also handle chemical diffusion of multiple dilute species, enabling the simulation of processes occurring in lab-on-chip devices and biosensors.
