Vortex ring and bubble interaction: Effects of bubble size on vorticity dynamics and bubble dynamics

S Biswas, RN Govardhan - Physics of Fluids, 2023 - pubs.aip.org
Bubbly turbulent flows involve complex interactions between bubbles and vortices, in which
their size ratio plays a critical role. The present work investigates an idealization, namely, the …

The role of breakup and coalescence in fine-scale bubble-induced turbulence. I. Dynamics

I Paul, B Fraga, MS Dodd, CCK Lai - Physics of Fluids, 2022 - pubs.aip.org
We study the effect of bubble breakup and coalescence on fine-scale dynamics of bubbly
turbulent flows using direct numerical simulations. We perform two different simulations of …

Numerical evaluation of the bubble dynamic influence on the characteristics of multiscale cavitating flow in the bluff body wake

Z Wang, H Cheng, RE Bensow, B Ji - International Journal of Multiphase …, 2024 - Elsevier
Unsteady cavitating flow around the bluff body widely existed in practical engineering fields.
This paper aims to investigate the physics involved in the multi-scale cavitating flow in the …

Spheres and fibers in turbulent flows at various Reynolds numbers

I Cannon, S Olivieri, ME Rosti - Physical Review Fluids, 2024 - APS
We perform fully coupled numerical simulations using immersed boundary methods of finite-
size spheres and fibers suspended in a turbulent flow for a range of Taylor-Reynolds …
