Cavitation by phase shift of focused shock waves inside a droplet
Samuele Fiorini, Guillaume T. Bokman, Anunay Prasanna +6
Localized cavitation in liquids and soft tissues, typically initiated by the rarefaction phase of high-amplitude ultrasound waves, is leveraged in several biomedical applications s…
Measurement of traveling pressure waves inside a droplet
Sayaka Ichihara, Samuele Fiorini, Yoshiyuki Tagawa +1
Shock wave-droplet interactions have been receiving increasing attention due to their relevance in aviation fuel combustion and minimally invasive medical treatments, yet quantifyi…
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…
High-resolution pressure imaging via background-oriented schlieren tomography: a spatiotemporal measurement for MHz ultrasound fields and hydrophone calibration
Sayaka Ichihara, Masato Yamagishi, Yuta Kurashina +2
In this work, the spatiotemporal pressure field of MHz-focused ultrasound is measured using a background-oriented schlieren technique combined with fast checkerboard demodulation a…
