DeboRheo v2.0: Improved Robustness for Geometrical VOF Simulations of Viscoelastic Two-Phase Flows
Daulet Izbassarov, Matthias Niethammer, Rahul Subburaj +5
We present DeboRheo v2.0, an unstructured, geometrically unsplit Volume-of-Fluid framework implemented in OpenFOAM for viscoelastic two-phase flows. Version 2.0 improves numerical…
Evaporation of a deformable droplet under convection
Faraz Salimnezhad, Metin Muradoglu
Evaporation of a deformable droplet under convection is investigated and the performance of the classical and Abramzon-Sirignano (A-S) models is evaluated. Using the Immersed Bound…
Bubbles-induced transition to elasto-inertial turbulence
Hafiz Usman Naseer, Daulet Izbassarov, Marco Edoardo Rosti +1
Interface-resolved direct numerical simulations are performed to investigate bubble-induced transition from laminar to elasto-inertial turbulent (EIT) state in a pressure-driven vi…
A Hybrid Immersed-Boundary/Front-Tracking Method for Interface-Resolved Simulation of Droplet Evaporation
Faraz Salimnezhad, Hasret Turkeri, Iskender Gokalp +1
A hybrid sharp-interface immersed-boundary/front-tracking (IB/FT) method is developed for interface-resolved simulation of evaporating droplets in incompressible multiphase flows.…
Dynamics of bubble migration in a square channel flow of a viscoelastic fluid
Hafiz Usman Naseer, Daulet Izbassarov, Zaheer Ahmed +1
Cross-stream migration of a deformable bubble is investigated computationally in a pressure-driven channel flow of a viscoelastic fluid via interface-resolved simulations. The flow…
Effects of elastoviscoplastic properties of mucus on airway closure in healthy and pathological conditions
O. Erken, B. Fazla, F. Romanò +3
Airway mucus is a complex material with both viscoelastic and viscoplastic properties that vary with healthy and pathological lung conditions. In this study, the effects of these c…
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…
