Abstract

Abstract: A non-Newtonian shear-thinning model is shown and applied to multiphase flow simulation in 3-D micro-tubes.The model is validated by comparing simulation and experimental results.Velocity simulated agrees well with experimental data and shows F-L effect in microscale hemodynamics.To investigate non-membrane hemodialysis,we simulate hemodialysis in a T-shape mixer.Simulation indicates that components with larger mass diffusion coefficient pervade sufficiently and they can be separated from other components.

Key words: non-Newtonian fluid, multiphase flow, mass transfer
