On the scaling of bubble interactions in dynamic turbulence: theoretical, numerical, and experimental study
Vivek Kumar, Prasoon Suchandra, Shivam Prajapati +2
This study investigates dilute bubbly decaying homogeneous isotropic turbulence at high Reynolds number using theory, direct numerical simulation, and experiments. The turbulent ki…
Dynamics of finger-type convection in double-diffusive instability
Mohammad Mohaghar, Anirban Bhattacharjee, Suhas S. Jain +1
Finger-type convection in double-diffusive instability (DDI) controls mixing and scalar transport in many stratified flows, yet a quantitative, finger-resolved description of the t…
Learning subgrid interfacial area in two-phase flows with regime-dependent inductive biases
Anirban Bhattacharjee, Luis H. Hatashita, Suhas S. Jain
The reliability of machine learning in multiscale physical systems depends on how physical structure is embedded into the learning process. We investigate this in the context of tu…
Mass-Transfer Control With Microbubbles in Highly Turbulent Decaying Flows
Vivek Kumar, Prasoon Suchandra, Jason Rom +3
We hypothesize that combining extreme turbulence with a minute reduction in surface tension (surface tension of the liquid) using surfactant provides a simple and scalable rou…
A model for transport of soluble surfactants in two-phase flows
Suhas S. Jain
In this work, we propose a novel transport model for soluble surfactants in two-phase flows. In a two-phase flow, the soluble surfactants can adsorb/desorb from/into the bulk of an…
Scalings and simulation requirements in two-phase flows
Luis H. Hatashita, Pranav Nathan, Suhas S. Jain
In this work, important two-phase flow scalings are derived, which enable the quantification of grid-point and time-step requirements as functions of Re, We, and Ca numbers. The ad…
