Regularized lattice Boltzmann Multicomponent models for low Capillary and Reynolds microfluidics flows

摘要

We present a regularized version of the color gradient lattice Boltzmann (LB)scheme for the simulation of droplet formation in microfluidic devices ofexperimental relevance. The regularized version is shown to providecomputationally efficient access to Capillary number regimes relevant todroplet generation via microfluidic devices, such as flow-focusers and the morerecent microfluidic step emulsifier devices.
