Restrictions on computing power make direct numerical simulation too expensive for complex flows; thus, the development of accurate large eddy simulation (LES) methods, which are industrially applicable and efficient, is required. This paper reviews recent findings about the leading order dissipation rate associated with high-resolution methods and improvements to the standard schemes for use in highly turbulent flows. Results from implicit LES are presented for a broad range of flows and numerical schemes, ranging from the second-order monotone upstream-centered schemes for conservation laws to very high-order (up to ninth-order) weighted essentially non-oscillatory schemes.

“…One solution is to integrate the equations between grid points to directly generate a set of 2nd-order finite-difference equations. Such is the approach of Implicit Large-Eddy Simulation (ILES) [Schumann, 1975, Fureby and Grinstein, 2002, Margolin and Rider, 2002, Hickel et al, 2006. This practice introduces two-dimensional cell-face averages as well as three-dimensional cell-volume averages, which must be related to each other.…”

Artificial fluid properties for large-eddy simulation of compressible turbulent mixing

An alternative methodology is described for Large-Eddy Simulation of flows involving shocks, turbulence and mixing. In lieu of filtering the governing equations, it is postulated that the large-scale behavior of an "LES" fluid, i.e., a fluid with artificial properties, will be similar to that of a real fluid, provided the artificial properties obey certain constraints. The artificial properties consist of modifications to the shear viscosity, bulk viscosity, thermal conductivity and species diffusivity of a fluid. The modified transport coefficients are designed to damp out high wavenumber modes, close to the resolution limit, without corrupting lower modes. Requisite behavior of the artificial properties is discussed and results are shown for a variety of test problems, each designed to exercise different aspects of the models. When combined with a 10th-order compact scheme, the overall method exhibits excellent resolution characteristics for turbulent mixing, while capturing shocks and material interfaces in crisp fashion.

“…ALDM is a nonlinear ¦nite volume method and incorporates free parameters in the discretization scheme, which can be used to control the truncation error. A physically motivated implicit SGS model that is consistent with turbulence theory is obtained through parameter calibration [28]. ALDM is implemented for Cartesian collocated grids and used to discretize the convective terms of the Navier Stokes equations.…”

In a joint e¨ort to develop a robust numerical tool for the simulation of injection, mixing, and combustion in liquid rocket engines at high pressure, a real-gas thermodynamics model has been implemented into two computational §uid dynamics (CFD) codes, the density-based INCA and a pressure-based version of OpenFOAM. As a part of the validation process, both codes have been used to perform large-eddy simulations (LES) of trans-and supercritical nitrogen injection. Despite the di¨erent code architecture and the di¨erent subgrid scale turbulence modeling strategy, both codes yield similar results. The agreement with the available experimental data is good.
