Direct Numerical Simulations of the Pulsating Flow over a Plane Wall

Direct Numerical Simulations of High Speed Flow over Cavity

Direct numerical simulations are used to investigate the effect of Mach number on the unsteady flow of an open cavity. The implicit solution is obtained for the compressible Navier-Stokes Equations using compact sixth-order spatial differencing coupled with tenth-order implicit filters. Results for transonic and subsonic flow over a two dimensional cavity are presented for the sound pressure le...

Numerical Study of Reynolds Number Effects on Flow over a Wall-Mounted Cube in a Channel Using LES

Turbulent flow over wall-mounted cube in a channel was investigated numerically using Large Eddy Simulation. The Selective Structure Function model was used to determine eddy viscosity that appeared in the subgrid scale stress terms in momentum equations. Studies were carried out for the flows with Reynolds number ranging from 1000 to 40000. To evaluate the computational results, data was compa...

Numerical simulation of pulsating turbulent channel flow

Direct and large-eddy simulations of the Navier–Stokes equations are used to study the pulsating flow in a channel. The cases examined span a wide range of frequencies of the driving pressure gradient, and encompass different physical behaviors, from the quasi-Stokes flow observed at high frequencies, to a quasisteady behavior at the lowest ones. The validity of the dynamic Smagorinsky model to...
