3D plug formation in T-junctions & complex cross shaped microchannels

Abstract eng:
We present three-dimensional direct numerical simulations of liquid-liquid plug formation in two kinds of microchannel configurations: circular T-junction and complex cross-junction microchannels. The simulations are carried out with a massively parallel two phase flow code, called BLUE. The method for the treatment of the fluid interfaces uses a hybrid Front Tracking/Level Set technique that defines the interface both by a discontinuous density field as well as by a triangular Lagrangian mesh. A static distance function represents the microchannel structures.
