A new mixed subgrid-scale model for large eddy simulation of turbulent drag-reducing flows of viscoelastic fluids |
Distributions of the Reynolds shear stress with y + for viscoelastic fluid cases at (a) We τ = 25, β = 0.8; (b) We τ = 40, β = 0.8 (“N” and “V” represent the Newtonian fluid and viscoelastic fluid, respectively). |
