【Abstract】

We have been studying various complex fluids with interesting functionalities under external fields, in which the external fields imply typical flow fields of laminar flow with most cases of rheological aspects and turbulent flow, electrical and magnetic fields. They include non-Newtonian fluid mechanics with flow fields of rod-climbing, turbulent drag reduction, suspension rheology of magnetic particles and Li-ion battery materials, polymer nanocomposites with clay and carbon nanotube, DNA dynamics under turbulent flow, rheology of PFPE lubricant and biodegradable polymers, in addition to conducting polymer based electrorheological(ER) fluids under an electric field, while magnetorheological (MR) suspensions have been characterized under an applied magnetic field.
Among these, polymer induced turbulent drag reduction along with DNA dynamics, ER; MR fluids, and Li-ion battery suspension rheology will be covered along with some introduction on material rheology. Specific focus will be put on the analysis of yield stress from ER and MR fluids.
