In this work, an improved anisotropic k-ε-v 2-f model based on the finite extensible nonlinear
elastic model with the Peterlin approximation for viscoelastic channel flows is proposed. This …

Numerical simulations were conducted on viscoelastic fluid flows in straight ducts with
different cross sections, for which the origin of secondary flows and influences of material …

Abstract Effects of microbubbles injection on friction drag in a turbulent boundary layer are
studied using large-eddy simulation. A flat-plate turbulent boundary layer with a Reynolds …

In this study, fully turbulent flow of non-Newtonian fluids is studied in a square periodic array
as a porous medium, with porosity ranging from 0.5 to 0.84. Large eddy simulation (LES) is …

For underwater drag reduction, one promising idea is to form a continuous gas or discrete
bubbly layer at the submerged surface. Owing to the lower viscosity of gas than of water, this …

To explore the drag-reducing characteristics of turbulent channel flows with surfactant
additive at relatively high Reynolds number from the perspectives of energy spectrum and …

We experimentally investigate the drag reduction characteristics of heated spheres falling
into water by using a high-speed camera. In 25-C water, with the increase of the sphere …

In this work, the drag-reducing mechanism of high-Reynolds-number turbulent channel flow
with surfactant additives is investigated by using large eddy simulation (LES) method. An N …

In this paper, to study the viscoelastic effect on isotropic turbulence without wall effects, a two
oscillating grid turbulence is built to investigate this phenomenon using particle image …

Large eddy simulation (LES) was performed for turbulent channel flow with and without
surfactant additives at Re τ= 590. Since turbulent channel flow can be divided into linear …
