Dynamics of pulsed laser-induced cavities on a liquid–gas interface: from a conical splash to a 'bullet'jet

JM Rosselló, H Reese, CD Ohl - Journal of Fluid Mechanics, 2022 - cambridge.org
The inception of a cavitation bubble in a liquid by focusing a short and intense laser pulse
near its free surface develops not only an upwards directed jet, but a second jet of opposite …

Crown formation from a cavitating bubble close to a free surface

Y Saade, M Jalaal, A Prosperetti… - Journal of fluid …, 2021 - cambridge.org
A rapidly growing bubble close to a free surface induces jetting: a central jet protruding
outwards and a crown surrounding it at later stages. While the formation mechanism of the …

[HTML][HTML] Comparison of boundary integral and volume-of-fluid methods for compressible bubble dynamics

S Li, Y Saade, D van der Meer, D Lohse - International journal of multiphase …, 2021 - Elsevier
Abstract The Boundary Integral Method (BIM) has been widely applied to simulate oscillating

[HTML][HTML] A multigrid solver for the coupled pressure-temperature equations in an all-Mach solver with VoF

Y Saade, D Lohse, D Fuster - Journal of Computational Physics, 2023 - Elsevier
We present a generalisation of the all-Mach solver of Fuster and Popinet (2018)[1] to
account for heat diffusion between two different compressible phases. By solving a two-way …

Bullet jet as a tool for soft matter piercing and needle-free liquid injection

JM Rosselló, CD Ohl - Biomedical Optics Express, 2022 - opg.optica.org
The collapse of a laser-induced vapor bubble near a solid boundary usually ends in a liquid
jet. When the boundary is from a soft material the jetting may pierce the liquid-solid interface …
