Ventilated Cavitation around a sphere through surface air injection at Re = 10,000
Soundararajan R, Anikesh Pal
We perform DNS of ventilated cavitation over a sphere at subcritical (Re=10,000). The flow is modeled as a homogeneous mixture of water and air, with the interface tracked using th…
Ultimate regime in Rayleigh-Darcy Convection
Garima Varshney, Anikesh Pal, Narsimha Reddy Rapaka
DNS of Rayleigh-Darcy convection in a 3D porous domain is performed at Ra to investigate heat-transfer scaling, thermal boundary-layer dynamics, and flow-structu…
Inverse cascade in zonal flows
Siddhant Mishra, Anikesh Pal
Zonal winds on Jovian planets play an important role in governing the cloud dynamics, transport of momentum, scalars, and weather patterns. Therefore, it is crucial to understand t…
Evolution of the rotating Rayleigh-Taylor instability under the influence of magnetic fields
