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 ...
Magnetohydrodynamic turbulence at moderate magnetic Reynolds number
(2004)
We consider the case of homogeneous turbulence in a conducting fluid that is exposed to a uniform external magnetic field at low to moderate magnetic Reynolds numbers (by moderate we mean here values as high as 20). When ...
A grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003
(2008)
Computational complexity theory inspires a grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003. A novel complexity analysis estimates that structured programming time grows at least quadratically with ...
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 ...
Complex effects in Large Eddy Simulations
(Springer, 2007)
Wetting of doped carbon nanotubes by water droplets
(2005)
We study the wetting of doped single- and multi-walled carbon nanotubes by water droplets using molecular dynamics simulations. Chemisorbed hydrogen is considered as a model of surface impurities. We study systems with ...
Rapid shear of initially anisotropic turbulence in a rotating frame?
(2007)
In the present study, we investigate, using inviscid rapid distortion theory, the evolution of sheared turbulence in a rotating frame as a function of the rotation rate (including stable, transitional, and unstable regimes), ...
