Analysis of Mesh Effects on Turbulent Flow Statistics
Ali Pakzad
Turbulence models, such as the Smagorinsky model herein, are used to represent the energy lost from resolved to under-resolved scales due to the energy cascade (i.e. non-linearity)…

On the determination of the grad-div criterion
V. Decaria, W. Layton, A. Pakzad +3
Grad-div stabilization, adding a term -gamma grad div u, has proven to be a useful tool in the simulation of incompressible flows. Such a term requires a choice of the coefficient…

Damping Functions correct over-dissipation of the Smagorinsky Model
Ali Pakzad
This paper studies the time-averaged energy dissipation rate for the combination of the Smagorinsky model and damping function. The Smagorins…
