Numerical studies towards practical large-eddy simulation
Jérôme Boudet, Joëlle Caro, L. Shao +1
Large-eddy simulation developments and validations are presented for an improved simulation of turbulent internal flows. Numerical methods are proposed according to two competing c…
Decay of scalar variance in isotropic turbulence in a bounded domain
Guillevic Lamaison, Wouter Bos, L. Shao +1
The decay of scalar variance in isotropic turbulence in a bounded domain is investigated. Extending the study of Touil, Bertoglio and Shao (2002; Journal of Turbulence, 03, 49) to…
Inertial range scaling of scalar flux spectra in uniformly sheared turbulence
Wouter J. T. Bos, Jean-Pierre Bertoglio
A model based on two-point closure theory of turbulence is proposed and applied to study the Reynolds number dependency of the scalar flux spectra in homogeneous shear flow with a…
Dynamics of spectrally truncated inviscid turbulence
Wouter J. T. Bos, Jean-Pierre Bertoglio
The evolution of the turbulent energy spectrum for the inviscid spectrally truncated Euler equations is studied by closure calculations. The observed behavior is similar to the one…
Spectral imbalance and the normalized dissipation rate of turbulence
Wouter J. T. Bos, L. Shao, Jean-Pierre Bertoglio
The normalized turbulent dissipation rate is studied in decaying and forced turbulence by direct numerical simulations, large-eddy simulations, and closure calculations. A la…
A single-time two-point closure based on fluid particle displacements
Wouter Bos, Jean-Pierre Bertoglio
A new single-time two-point closure is proposed, in which the equation for the two-point correlation between the displacement of a fluid particle and the velocity allows one to est…
