Dynamics of bubble migration in a square channel flow of a viscoelastic fluid

Autor: Naseer, Hafiz Usman, Izbassarov, Daulet, Ahmed, Zaheer, Muradoglu, Metin

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 equations are solved fully coupled with the Giesekus model equations

Autor: Ahmed, Zaheer, Izbassarov, Daulet, Costa, Pedro, Muradoglu, Metin, Tammisola, Outi

Publikováno v: Computers and Fluids 202 (2020) 104717

Interface-resolved direct numerical simulations are performed to examine the combined effects of soluble surfactant and viscoelasticity on the structure of a bubbly turbulent channel flow. The incompressible flow equations are solved fully coupled wi

Polymer drag reduction in surfactant-contaminated turbulent bubbly channel flows

Autor: Izbassarov, Daulet, Ahmed, Zaheer, Costa, Pedro, Vuorinen, Ville, Tammisola, Outi, Muradoglu, Metin

Publikováno v: Physical Review Fluids 6 (2021) 104302

Polymer additives are commonly utilized to manipulate bubbly flows in various applications. Here, we investigate the effects of clean and contaminated bubbles driven upwards (upflow) in Newtonian and viscoelastic turbulent channel flows. Interface-re
