Flow birefringence measurement in a radial Hele-Shaw cell considering three-dimensional effects
Misa Kawaguchi, William Kai Alexander Worby, Yuto Yokoyama +3
Flow birefringence measurement is an emerging technique for visualizing stress fields in fluid flows. This study investigates flow birefringence in the steady radial Hele-Shaw flow…

Extending flow birefringence analysis to combined extensional-shear flows via Jeffery-Hamel flow measurements
Miu Kobayashi, William Kai Alexander Worby, Misa Kawaguchi +3
This study investigates the relationship between phase retardation and strain rates in combined extensional-shear flows using the Jeffery-Hamel flow formalism, which yields an anal…

Experimental study on the relationship between extensional and shear rheology of low-viscosity power-law fluids
Yuzuki Matsumoto, Misa Kawaguchi, Yoshiyuki Tagawa
This paper investigates the relationship between extensional and shear viscosity of low-viscosity power-law fluids. We show the first experimental evidence of the conditions satisf…
