Complex Fluids
Lately, the rheology of complex fluids has been attracting many attentions due to its importance and applicability, especially in biological systems. We are currently working on the study of the flow of non-Newtonian fluids. In particular, we are examining suspension flows in micro-fluid systems by means of particle modeling schemes such as the Diffusive Flux Model (DFM) and the Suspension Balance Model (SBM).
