Turbulence impacts synthetic methanol production in a square duct flow: a direct numerical simulation (DNS) study
Marko Korhonen, Daulet Izbassarov, Judit Nyári +2
Improving the synthetic methanol production efficiency is essential for adopting carbon-neutral methanol technologies. In the present computational fluid dynamics (CFD) study, we i…
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…
Dynamics of an elastoviscoplastic droplet in a Newtonian medium under shear flow
Daulet Izbassarov, Outi Tammisola
The dynamics of a single elastoviscoplastic (EVP) drop immersed in plane shear flow of a Newtonian fluid is studied by 3D direct numerical simulations using a finite-difference and…
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…
The effect of droplet coalescence on drag in turbulent channel flows
Ianto Cannon, Daulet Izbassarov, Outi Tammisola +2
We study the effect of droplet coalescence on turbulent wall-bounded flows, by means of direct numerical simulations. In particular, the volume-of-fluid and front-tracking methods…
