Advances and challenges of applied large-eddy simulation

High accuracy flow simulations: Advances and challenges for future needs in aeronautics

“…The turbulence modelling is ranging from the Reynolds Averaged Navier-Stokes equations (RANS [6]) to the Direct Numerical Simulations (DNS [7,8]), pass-through Large-Eddy Simulations (LES) approaches, which reviews are done in the reference [9][10][11]. In order to extend LES to high Reynolds number flows new methods have recently been developed.…”

Simulation of viscous flows with undulatory boundaries: Part II. Coupling with other solvers for two-fluid computations

“…For the application to more realistic problems, large-eddy simulation (LES) can be used, which has been facilitated by the recent developments in subgrid-scale stress and wall function models (see e.g. [6,26,17,2]; also see the review by [8]). Here, we focus on the development of basic numerical coupling scheme, and we limit our discussion to DNS.…”

Modelling transition due to backward-facing steps using the laminar kinetic energy concept

“…An alternative approach is LES where the large scales in the flow are simulated and turbulence below the inertial sub-range is modelled and assumed universal following Kolmogorov's Universal Equilibrium Theory. Excellent reviews covering the working principles of LES as well as challenges faced in its application can be found in [11,12]. An advantage of LES (when compared to DNS) is that the smallest turbulent scales are modelled, as a result the mesh density require-ment is reduced, with further reductions by modelling the boundary layer near walls in wall-bounded flows [13,14].…”
