From stratified wakes to rotor–stator flows by an SVV–LES method
نویسنده
چکیده
We extend a large-eddy simulation (LES) methodology, based on using the spectral vanishing viscosity (SVV) method to stabilize spectral collocation approximations, from the Cartesian to the cylindrical geometry. The capabilities of the SVV–LES approach are illustrated for two very different physical problems: (1) the influence of thermal stratification on the wake of a cylinder, and (2) the instabilities that develop in transitional and fully turbulent rotor–stator flows.

A spectral vanishing viscosity for the LES of turbulent flows within rotating cavities
A spectral vanishing viscosity technique (SVV) is presented for the simulation of 3D turbulent incompressible flows within a rotor–stator cavity. One characteristic of this technique is that the SVV is active only for the short length scales, a feature which is reminiscent of Large Eddy Simulation models. The Spectral Vanishing Viscosity, first introduced by E. Tadmor for the inviscid Burgers e...
متن کاملHigh-order Large Eddy Simulations of Confined Rotor-Stator Flows
In many engineering and industrial applications, the investigation of rotating turbulent flow is of great interest. In rotor-stator cavities, the centrifugal and Coriolis forces have a strong influence on the turbulence by producing a secondary flow in the meridian plane composed of two thin boundary layers along the disks separated by a non-viscous geostrophic core. Most numerical simulations ...
متن کاملParallel Computations of Unsteady Three-Dimensional Flows in a High Pressure Turbine
Steady (RANS) and unsteady (URANS) numerical simulations of three-dimensional transonic flow in a high-pressure turbine have been conducted. The results are compared by evaluating differences in contours of total pressure loss, contours of static pressure and wakes. Significant differences have been observed in these parameters, both qualitative and quantitative, which demonstrate that URANS si...
متن کاملSpectral Vanishing Viscosity Method for High-order Les : Computation of the Dissipation Rates
The spectral vanishing viscosity (SVV) method has recently appeared of interest for the large-eddy simulation (LES) of turbulent flows. Here we show that the SVV-LES approach allows to easily compute turbulent quantities, like the dissipation rates of the turbulent kinetic energy or of the variance of a passive scalar and to clearly discern the subgrid and viscous contributions. Results obtaine...
متن کاملEffect of the Axial Spacing between Rotor and Stator with Regard to the Indexing in an Axial Compressor
An experimental investigation was carried out to examine the influence of the axial spacing between rotor and stator. The test facility of the Swiss Federal Institute of Technology is made up of an inlet guide vane (IGV), a rotor and a stator. Temperature and aerodynamic measurements determined the characteristics of the compressor stage. Data were acquired over a range of flow coefficients for...
