Post Image Recently, microfluidic devices for non-Newtonian fluids have been receiving great attention because the intrinsic nonlinear elastic forces arising in pressure-driven flows of diluted polymer solutions can drive suspended particles away from walls and toward the mid-plane of the channel. This phenomenon is primarily attributed to the non-uniform distribution of the normal stress difference of a non-Newtonian fluid in asymmetric, confined geometries.Cross-sectional position of particles suspended in a Newtonian fluid flow in a straight microtube. The values for the diameter of ...   내용 보기
