LES of the flow past a rectangular cylinder using the immersed boundary concept
(2003)
Incompressible turbulent flow past a long square cylinder is investigated using large eddy simulations LES). Results are presented and compared with available experimental databases for a Reynolds number Red = 22 000. The ...
Efficient treatment of complex geometries for large eddy simulations of turbulent flows
(2004)
Incompressible turbulent flow over a backward facing step at Reh=5100 is investigated by large eddy simulations (LES). The ratio of the oncoming boundary layer thickness δ to the step height h was set to 1.2. Additionally ...
Structure-based turbulence modeling for wall-bounded flows
(2000)
The performance of Reynolds stress transport (RST) models in non-equilibrium flows is limited by the lack of information about two dynamically important effects: The role of energy-containing turbulence structure ...
The transport of a passive scalar in magnetohydrodynamic turbulence subjected to mean shear and frame rotation
(2007)
We consider the transport of a passive scalar under the influence of homogeneous turbulence in a conducting fluid that is exposed to a uniform external magnetic field while being sheared in fixed and rotating frames. The ...
Statistical measures of structural anisotropy in MHD turbulence subjected to mean shear and frame rotation
(2006)
We consider homogeneous turbulence in a conducting fluid that is exposed to a uniform external magnetic field while being sheared in fixed and rotating frames. We take both the frame-rotation axis and the applied magnetic ...
A simplified structure-based model using standard turbulence scale equations: computation of rotating wall-bounded flows
(2006)
Two linear eddy-viscosity models, the v2-f and k-ω models, have been combined with an algebraic structure-based algorithm for the evaluation of the Reynolds stresses. This closure was originally designed as an integral ...
Rapidly sheared homogeneous stratified turbulence in a rotating frame
(2007)
Rapid distortion theory is applied to stratified homogeneous turbulence that is sheared in a rotating frame. Insight into the stabilizing and destabilizing effects of the combined stratification and frame rotation is gained ...
Linear analysis of generalized turbulent hyperbolic flow in a rotating frame
(2007)
We apply inviscid rapid distortion theory to the generalized case of turbulent hyperbolic flow in a rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the frame rotation rate. ...
On the linear stability of turbulent plane strain flow in a rotating frame
(2007)
We apply inviscid rapid distortion theory to the limiting hyperbolic case of turbulent plain strain flow in a rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the frame ...
Structure-based turbulence model: Application to a rotating pipe flow
(2002)
A new approach for modeling the one-point turbulence statistics, which takes into account the information on turbulence structure, has been suggested in Kassinos and Reynolds (Report TF-61, Thermosciences Division, Department ...
