Understanding Turbulence in Active Microscale Mixers

We are studying the effects of a variable electric field to drive mixing in a micromixer and the possible generation of turbulence in the process. Iso-surfaces of velocity are shown here, where blue indicates a low speed and red a high speed. We are also examining entropy generation rates due to advection and diffusion to understand the interplay of irreversibility increase due to entropy generation and improved mixing.
