Investigation of coalescence and pinch-off processes of a self-rewetting drop interacting with a liquid layer
Bashir Elbousefi, William Schupbach, Kannan N. Premnath +1
Self-rewetting fluids (SRFs), such as long-chain aqueous alcohols, are a special class of liquids with surface tension that is anomalously dependent quadratically on temperature, r…
Fokker-Planck Model Based Central Moment Lattice Boltzmann Method for Effective Simulations of Thermal Convective Flows
William Schupbach, Kannan Premnath
The Fokker-Planck (FP) equation represents the drift-diffusive processes in kinetic models. It can also be regarded as a model for the collision integral of the Boltzmann-type equa…
A Robust Lattice Boltzmann Method for Interface-Bound Transport of a Passive Scalar: Application to Surfactant-Laden Multiphase Flows
William Schupbach, Kannan Premnath
The transport of a passive scalar restricted on interfaces, which is advected by the fluid motions have numerous applications in multiphase transport phenomena. A prototypical exam…
Fokker-Planck Central Moment Lattice Boltzmann Method for Effective Simulations of Fluid Dynamics
William Schupbach, Kannan Premnath
We present a new formulation of the central moment lattice Boltzmann (LB) method based on a continuous Fokker-Planck (FP) kinetic model, originally proposed for stochastic diffusiv…
Investigation of Surfactant-Laden Bubble Migration Dynamics in Self-Rewetting Fluids using Lattice Boltzmann Method
Bashir Elbousefi, William Schupbach, Kannan N. Premnath +1
Self-rewetting fluids (SRFs) (e.g., aqueous solutions of long-chain alcohols) show anomalous nonlinear (quadratic) variations of surface tension with temperature involving a positi…
