Direct numerical simulation tests of eddy viscosity in two dimensions
نویسنده
چکیده
Two-parametric eddy viscosity (TPEV) and other spectral characteristics of two-dimensional (2D) turbulence in the energy transfer sub-range are calculated from direct numerical simulation (DNS) with 5122 resolution. The DNS-based TPEV is compared with those calculated from the test field model (TFM) and from the renormalization group (RG) theory. Very good agree-

Numerical Simulation of Separation Bubble on Elliptic Cylinders Using Three-equation k-? Turbulence Model
Occurrence of laminar separation bubbles on solid walls of an elliptic cylinder has been simulated using a recently developed transitional model for boundary layer flows. Computational method is based on the solution of the Reynolds averaged Navier-Stokes (RANS) equations and the eddy-viscosity concept. Transitional model tries to simulate streamwise fluctuations, induced by freestream turbulen...
متن کاملEffects of Eddy Viscosity on Time Correlations in Large Eddy Simulation
Subgrid-scale (SGS) models for large eddy simulation (LES) have generally been evaluated by their ability to predict single-time statistics of turbulent ows such as kinetic energy and Reynolds stresses. Recent applications of large eddy simulation to the evaluation of sound sources in turbulent ows, a problem in which time correlations determine the frequency distribution of acoustic radiation,...
متن کاملNumerical Analysis of Two Ensemble Eddy Viscosity Models of Fluid Motion
This report extends a recent method that calculates an ensemble of solutions of the Navier-Stokes equations efficiently to higher Reynolds number flows. To do so herein we develop and analyze two ensemble eddy viscosity models that do not obviate the good algorithmic properties of the ensemble method. The combined approach of ensemble time stepping and ensemble eddy viscosity modelling has othe...

متن کاملNew subgrid-scale models for large-eddy simulation of Rayleigh-Bénard convection
At the crossroad between flow topology analysis and the theory of turbulence, a new eddy-viscosity model for Large-eddy simulation has been recently proposed by Trias et al .[PoF, 27, 065103 (2015)]. The S3PQR-model has the proper cubic near-wall behaviour and no intrinsic limitations for statistically inhomogeneous flows. In this work, the new model has been tested for an air turbulent Rayleig...
