Spring 2024
A diffuse interface model to simulate a system of two immiscible liquids with surfactants is proposed. This model is based on a modified Ginzburg-Landau free energy functional to account for non-ionic soluble surfactants and couples the Navier-Stokes equations with two Cahn-Hilliard equations...

This work focuses on the implementation and validation of the implicit Total Variation Diminishing (TVD) schemes for modelling of two-dimensional multiphase flow. The TVD schemes are designed to mitigate the numerical diffusion at the interface where discontinuities of fluid properties exist...

Spring 2018
This work examined liquid/liquid drawdown. Two tank geometries (ST and CIST) and three sets of impellers (PBT, A310, RT) were used. Water and Canola oil were the continuous and dispersed phases, respectively, with a holdup of oil of either 10% or 30%. First, the point of initial disruption of the...

The focus of this study is to gain a fundamental understanding of liquid-liquid dispersion formation in homogeneous isotropic turbulence. This information is crucial to improve the reliability of existing models that describe drop breakup in turbulent flow. These models inherit numerous...
