Turbulent flows laden with large, deformable drops are ubiquitous in nature and in a wide
range of industrial processes. Prediction of the interactions between drops, which deform …

In this work, we compute numerically breakage/coalescence rates and size distribution of
surfactant-laden droplets in turbulent flow. We use direct numerical simulation of turbulence …

With the aim of efficiently simulating three-dimensional multiphase turbulent flows with a
phase-field method, we propose a new discretization scheme for the biharmonic term (the …

We study the dynamics of capillary waves at the interface of a two-layer stratified turbulent
channel flow. We use a combined pseudo-spectral/phase field method to solve for the …

We investigate the effect of density and viscosity differences on a swarm of large and
deformable bubbles dispersed in a turbulent channel flow. For a given shear Reynolds …

We numerically investigate turbulent Rayleigh–Bénard convection through two immiscible
fluid layers, aiming to understand how the layer thickness and fluid properties affect the heat …

We study the problem of drag reduction (DR) in a lubricated conduit, in which a thin layer of
low-viscosity (eg, water) fluid is injected in the near-wall region and facilitates the transport …

We use direct numerical simulation (DNS) to study drag reduction in a lubricated channel, a
flow instance in which a thin layer of lubricating fluid is injected in the near-wall region so as …

It is commonly accepted that the breakup criteria of drops or bubbles in turbulence is
governed by surface tension and inertia. However, also buoyancy can play an important role …

Immiscible and incompressible liquid–liquid flows are considered in a Taylor–Couette
geometry and analysed by direct numerical simulations coupled with the volume-of-fluid …
