Large-Eddy Simulation of Axisymmetric Compression Corner Flow [PDF]
The Wall-Modeled Large Eddy Simulation (WMLES) approach is used to study the interaction of a shock wave with a high Reynolds number turbulent boundary layer. Since the near wall region is modeled, high Reynolds number turbulent flows can be simulated at

Compressive sensing adaptation for polynomial chaos expansions
, 2018 Basis adaptation in Homogeneous Chaos spaces rely on a suitable rotation of the underlying Gaussian germ. Several rotations have been proposed in the literature resulting in adaptations with different convergence properties.

Towards Efficient Hybrid RANS–LES for Industrial Aeronautical Applications
Flow, Turbulence and CombustionAbstract Three complementary approaches for reducing the grid-resolution requirements in hybrid RANS–LES computations, namely (a) the use of wall functions, (b) the application of locally embedded WMLES instead of global WMLES, as well as (c) local grid adaptation in LES regions, are assessed for different test cases up to an industry ...

A Hybrid Model Based on Continuous Fluctuation Corrections [PDF]
, 2008 A novel method is proposed for blending RANS and VMS-LES approaches in a hybrid model. To this purpose, the flow variables are decomposed in a RANS part (i.e.

Joint RANS/LES Modeling of Flameless Combustion
Energy and Power Engineering, 2011 We present our timesaving joint RANS/LES approach (we originally developed it for numerical simulations of turbulent premixed combustion) to simulate flameless combustion with separate injection of gas fuel and strong exhaust gas recirculation. It is based on successive RANS/LES numerical modeling where part of the information (stationary average ...
