Jet coronation: Coexistence of compressible and incompressible dynamics
H. Watanabe, K. Hashimoto, W. K. A. Worby +4
This paper is associated with a poster winner of a 2025 American Physical Society's Division of Fluid Dynamics (DFD) Gallery of Fluid Motion Award for work presented at the DFD Gal…
Full-component reconstruction of three-dimensional fluid stress tensors
Shunsuke Kumagai, Shun Miyatake, Ryusuke Cho +5
Forces govern how fluids deform biological tissues, regulate cardiovascular function, and determine the performance and failure of soft materials. Recent advances in flow birefring…
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…
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…
Examination of flow birefringence induced by the shear components along the optical axis using a parallel-plate-type rheometer
William Kai Alexander Worby, Kento Nakamine, Yuto Yokoyama +2
In this study, the concept of rheo-optics is applied that explores the flow birefringence caused by stress components along the optical axis of the camera since it is often overloo…
