Maximum updraft velocity beyond CAPE: the role of boundary layer dynamics and pressure perturbations
Bety Pechacova, Alejandro Casallas, Tom Beucler +2
Deep convective updraft velocities play a key role in the Earth's climate system, influencing precipitation extremes, lightning, and the planetary energy budget. While Convective A…
Dynamics and Scaling of Internally Cooled Convection
Lokahith Agasthya, Caroline Muller
Our goal is to investigate fundamental properties of the system of internally cooled convection. The system consists of an upward thermal flux at the lower boundary, a mean tempera…
Reconstructing Rayleigh-Benard flows out of temperature-only measurements using Physics-Informed Neural Networks
Patricio Clark Di Leoni, Lokahith Agasthya, Michele Buzzicotti +1
We investigate the capabilities of Physics-Informed Neural Networks (PINNs) to reconstruct turbulent Rayleigh-Benard flows using only temperature information. We perform a quantita…
Large-scale convective flow sustained by thermally active Lagrangian tracers
Lokahith Agasthya, Andreas Bartel, Luca Biferale +2
Non-isothermal particles suspended in a fluid lead to complex interactions -- the particles respond to changes in the fluid flow, which in turn is modified by their temperature ano…
Reconstructing Rayleigh-Bénard flows out of temperature-only measurements using nudging
Lokahith Agasthya, Patricio Clark Di Leoni, Luca Biferale
Nudging is a data assimilation technique that has proved to be capable of reconstructing several highly turbulent flows from a set of partial spatiotemporal measurements. In this s…
Understanding droplet collisions through a model flow: Insights from a Burgers vortex
Lokahith Agasthya, Jason R. Picardo, S. Ravichandran +2
We investigate the role of intense vortical structures, similar to those in a turbulent flow, in enhancing collisions (and coalescences) which lead to the formation of large aggreg…
Flow structures govern particle collisions in turbulence
Jason R. Picardo, Lokahith Agasthya, Rama Govindarajan +1
The role of the spatial structure of a turbulent flow in enhancing particle collision rates in suspensions is an open question. We show and quantify, as a function of particle iner…
