Large-eddy simulation of transonic turbulent flow over a bump
Transonic turbulent boundary-layer flow over a circular-arc bump has been computed by high-resolution large-eddy simulation of the compressible Navier–Stokes equations. The inflow turbulence was prescribed using a new technique, in which known dynamical features of the inner and outer part of the boundary-layer were exploited to produce a standard turbulent boundary-layer within a short distanc...

15 صفحه اولApplied large eddy simulation.
Large eddy simulation (LES) is now seen more and more as a viable alternative to current industrial practice, usually based on problem-specific Reynolds-averaged Navier-Stokes (RANS) methods. Access to detailed flow physics is attractive to industry, especially in an environment in which computer modelling is bound to play an ever increasing role. However, the improvement in accuracy and flow d...
متن کاملAdaptive Large Eddy Simulation
This project is focused on development of a novel approach, called Stochastic Coherent Adaptive Large Eddy Simulation (SCALES) for modeling and simulation of turbulent flows. The approach comes from the realization of the deficiency of the current Large Eddy Simulation (LES) approach, which resolves only the large-scale motions instead of coherent energy containing flow structures. The SCALES a...
متن کاملNumerical Simulation of Transonic Buffet on Swept Wing of Supercritical Airfoils
This paper presents transonic buffet simulations over a swept wing of supercritical airfoils with Unsteady Reynolds-Averaged Navier-Stokes (URANS) and Detached-Eddy Simulation (DES) methods. The NASA SC(2)-0714 airfoil is used as wing profile. Computations are conducted at free-stream Mach numbers from 0.72 to 0.84 for Reynolds number 45.0 × 10 based on aerodynamic chord length. Firstly, 2D NAS...
