Polymer drag reduction in surfactant-contaminated turbulent bubbly channel flows
Daulet Izbassarov, Zaheer Ahmed, Pedro Costa +3
Polymer additives are commonly utilized to manipulate bubbly flows in various applications. Here, we investigate the effects of clean and contaminated bubbles driven upwards (upflo…
Turbulent bubbly channel flows: Effects of soluble surfactant and viscoelasticity
Zaheer Ahmed, Daulet Izbassarov, Pedro Costa +2
Interface-resolved direct numerical simulations are performed to examine the combined effects of soluble surfactant and viscoelasticity on the structure of a bubbly turbulent chann…
Near-wall turbulence modulation by small inertial particles
Pedro Costa, Luca Brandt, Francesco Picano
We use interface-resolved simulations to study near-wall turbulence modulation by small inertial particles, much denser than the fluid, in dilute/semi-dilute conditions. We conside…
Aerodynamically-driven rupture of a liquid film by turbulent shear flow
Melissa Kozul, Pedro S. Costa, James R. Dawson +1
The rupture of a liquid film due to co-flowing turbulent shear flows in the gas phase is studied using a volume-of-fluid method. To simulate this multiphase problem, we use a simpl…
GPU acceleration of CaNS for massively-parallel direct numerical simulations of canonical fluid flows
Pedro Costa, Everett Phillips, Luca Brandt +1
This work presents the GPU acceleration of the open-source code CaNS for very fast massively-parallel simulations of canonical fluid flows. The distinct feature of the many-CPU Nav…
A volume-of-fluid method for interface-resolved simulations of phase-changing two-fluid flows
Nicolò Scapin, Pedro Costa, Luca Brandt
We present a numerical method for interface-resolved simulations of evaporating two-fluid flows based on the volume-of-fluid (VoF) method. The method has been implemented in an eff…
