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…
Thermocapillary Convection in Superimposed Layers of Self-Rewetting Fluids: Analytical and Lattice Boltzmann Computational Study
Bashir Elbousefi, William Schupbach, Kannan N. Premnath +1
Self-rewetting fluids (SRFs), such as aqueous solutions of long-chain alcohols, exhibit anomalous quadratic dependence of surface tension on temperature having a minimum and with a…
Central Moment Lattice Boltzmann Method using a Pressure-based Formulation for Multiphase Flows at High Density Ratios and including Effects of Surface Tension and Marangoni Stresses
Farzaneh Hajabdollahi, Kannan Premnath, Samuel W. J. Welch
Simulation of multiphase flows require coupled capturing or tracking of the interfaces in conjunction with the solution of fluid motion often occurring at multiple scales. We will…
Cascaded Lattice Boltzmann Method based on Central Moments for Axisymmetric Thermal Flows Including Swirling Effects
Farzaneh Hajabdollahi, Kannan N. Premnath, Samuel W. J. Welch
A cascaded lattice Boltzmann (LB) approach based on central moments and multiple relaxation times to simulate thermal convective flows, which are driven by buoyancy forces and/or s…
