Title of the Talk
"Multiphase non-Newtonian pseudoplastic liquid systems".
Non-Newtonian pseudoplastic liquid is the commonly encountered time independent fluid. This fluid is characterized by an viscosity which decreases with the increasing shear rate. This liquids often used in industries like polymer processing, petrochemical and refinery, mineral recovery, food processing, biomedical engineering, biochemical engineering, waste water treatment. Introduction of another phase in the pseudoplastic liquid the viscosity of the system can change. The change of viscosity should utilize in different unit operations. This lecture will describe the advantages of this properties in gas-liquid, solid-liquid systems like pipe flow, bubble column, taper bubble column, fluidization and inverse fluidization etc.
