SUMMARY:Rheometry with Non-Rheometric Flows
DESCRIPTION:Speaker: Prof. Wook Ryol Hwang (Professor\, School of Mechani
 cal Engineering\, Gyeongsang National University\, Kor)\nHost: Patrick An
 derson\n\nNovel industrial rheometric approaches will be introduced for m
 easuring viscoelasticity of a liquid as well as viscosity in complex flow
  fields. Modeling schemes based on energy dissipation rate will be introd
 uced to establish the relationship between macroscopic flow parameters (t
 orque\, pressure drop\, rotational speed\, flow rate\, deflection angle\,
  etc.) and rheometric variables (shear stress\, shear rate\, shear strain
 \, viscosity\, shear modulus\, etc.). Starting from the general flow quan
 tification method for both rotational and pressure-driven flows\, several
  application problems will be discussed to measure the viscosity as a fun
 ction of shear rate and more importantly to measure the viscoelasticity i
 n both linear and non-linear regimes. Example flow fields for viscoelasti
 city include (1) agitator systems with impellers and a vessel\, (2) a vis
 cometer-like system (a rotating object in a liquid pool)\, (3) general pr
 essure-driven pipe flows.
