...Kaushik Balakrishnan; Josette Bellan A formulation is developed using volume-averaging and the concept of added mass to derive a hyperbolic system of governing equations for modeling turbulent, dense granular flows. The large eddy simulations (LES) framework is employed for the fluid phase, whereas...

...Puxuan Li; Matthew Campbell; Ning Zhang; Steve J. Eckels This study proposes a numerical model to collect and analyze relationships between flow structures and drag forces on a microfin enhanced surface. We utilized a large eddy simulation (LES) with a localized, dynamic kinetic energy, subgrid...

... airfoil with sinusoidal WLE that bears a wavelength of 25% and an amplitude of 5% of the mean chord length and straight-leading-edge (SLE). A large eddy simulation (LES) turbulence model was used. This includes the dynamic control of unsteady flow separation, the three-dimensional vortical structure...

... nonreflecting outflow boundary conditions. A large eddy simulation (LES) model for turbulence is benchmarked with existing experimental data. After validation of the present model against experimental results for a 90 deg pipe bend, a detailed numerical study aimed at reproducing experimental flow measurements...

...I. B. Celik; Z. N. Cehreli; I. Yavuz In the light of rapidly increasing applications of large-eddy simulations (LES), it is deemed necessary to impose some quality assessment measures for such studies. The verification of LES calculations is difficult because of the fact that both the subgrid scale...
