Planetary core‐style rotating convective flows in paraboloidal laboratory experiments

TL Lonner, A Aggarwal… - Journal of Geophysical …, 2022 - Wiley Online Library
Turbulent convection in a planet's outer core is simulated here using a thermally‐driven, free
surface paraboloidal laboratory annulus. We show that the rapidly rotating convection …

Melting driven by rotating Rayleigh–Bénard convection

S Ravichandran, JS Wettlaufer - Journal of Fluid Mechanics, 2021 - cambridge.org
We study numerically the melting of a horizontal layer of a pure solid above a convecting
layer of its fluid rotating about the vertical axis. In the rotating regime studied here, with …

The combined effects of buoyancy, rotation, and shear on phase boundary evolution

S Ravichandran, S Toppaladoddi… - Journal of Fluid …, 2022 - cambridge.org
We use well-resolved numerical simulations to study the combined effects of buoyancy,
pressure-driven shear and rotation on the melt rate and morphology of a layer of pure solid …

Stepwise transitions in spin-up of rotating Rayleigh–Bénard convection

D Noto, Y Tasaka, T Yanagisawa… - Journal of Fluid …, 2021 - cambridge.org
Transient behaviours during spin-up in rotating Rayleigh–Bénard convection (RBC) with
imposed rotation were quantitatively investigated in laboratory experiments. Horizontal and …

Direct numerical simulation of a moist cough flow using Eulerian approximation for liquid droplets

R Singhal, S Ravichandran… - International Journal of …, 2021 - Taylor & Francis
The COVID-19 pandemic has inspired several studies on the fluid dynamics of respiratory
events. Here, we propose a computational approach in which respiratory droplets are …
