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…
Bubble coalescence dynamics in a high-Reynolds number decaying turbulent flow
Vivek Kumar, Prasoon Suchandra, Ardalan Javadi +2
This study experimentally investigates bubble size evolution and void fraction redistribution in an unexplored, coalescence-dominated regime of decaying turbulent bubbly flow. The…
Accurate calculation of bubble and droplet properties in diffuse-interface two-phase simulations
Pranav J. Nathan, Suhas S. Jain
In this paper, we address the challenge of accurately calculating droplet/bubble properties (e.g., volume, number) in diffuse-interface two-phase flow simulations. Currently, flood…
Stationary states of forced two-phase turbulence
Suhas S Jain, Ahmed Elnahhas
In this work, we perform numerical simulations of forced two-phase isotropic turbulence to study the stationary states of a two-phase mixture. We first formulate three different ap…
