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…
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…
