CFD model in OpenFOAM for electrowetting-driven two phase flow microfluidics

Ivo Roghair, formerly at PCF and now at Tu/e, and co-workers published a CFD model to described the dynamics of the motion of drops in the presence of electric fields in the journal Microfluidics Nanofluidics. The model solves the Navier Stokes equations and the Poisson equation to simultaneously capture the coupled dynamics of the oil-water fluid system and the electric charges using a volume-of-fluid method with front tracking. The model is implemented in the open access environment OpenFOAM and includes a specific model of contact line dynamics based on the Cox-Voinov approach. The functionality of the versatile code is demonstrated for the specific application of an electrowetting-based display pixel.

The work was carried out in collaboration with M. Musterd, M. Kreutzer, and C. Kleijn at the Technical University of Delft. The paper is freely accessible at http://link.springer.com/article/10.1007/s10404-015-1581-5.
