Phase-change contrast agents (PCCAs) for ultrasound-based applications have resulted in
novel ways of approaching diagnostic and therapeutic techniques beyond what is possible …

Bubbles are always encountered for gas–liquid two-phase flow in microchannels, and have
potential applications in chemical engineering, polymer engineering, food engineering, and …

Pulmonary transit of agitated contrast (PTAC) occurs to variable extents during exercise. We
tested the hypothesis that the onset of PTAC signifies flow through larger-caliber vessels …

In gas–liquid two-phase microreactors, bubbles are prone to breakup when passing through
complex internal channels. The bubble breakup is not only conducive to mass transfer but …

The aim of this work is to investigate experimentally the bubble breakup in a microfluidic T-
junction divergence using a high-speed digital camera and a micro-Particle Image …

Two-phase interface fluid, bubble or droplet, has shown broad application potential in oil
and gas field development, contaminated soil remediation, and medical treatment. These …

Acoustic droplet vaporization (ADV) shows promise for spatially and temporally targeted
tissue occlusion. In this study, substantial tissue occlusion was achieved in operatively …

In the present paper we present a phenomenological description of droplet dynamics in a
bifurcating channel that is based on three-dimensional numerical experiments using the …

Acoustic droplet vaporization in a rigid tube at body temperature was investigated
experimentally using an ultra-high speed camera. This study was motivated by gas …

We present experimental, numerical, and theoretical studies of droplet flows in
hydrodynamic networks. Using both millifluidic and microfluidic devices, we study the …
