Consistency improved random flow generation method for large eddy simulation of atmospheric boundary layer
TL;DR: In this paper , a new inflow turbulence generation (ITG) method, the consistency improved random flow generation (CIRFG) method is proposed to model the spatial correlations and cross-correlations between different velocity components by explicitly embedding turbulence characteristics, thus it can be used widely in arbitrary situations without any empirical parameters.

A-posteriori assessment of Large-Eddy Simulation subgrid-closures for momentum and scalar fluxes in a turbulent premixed burner experiment
TL;DR: In this paper , the impact of the choice of the subgrid-model for reactive flows in LES in the context of tabulated chemistry using well known and recently suggested modifications of eddy viscosity and scale-similarity-type models is investigated.

Flame structure analysis and flamelet modeling of turbulent pulverized solid fuel combustion with flue gas recirculation
Xu Wen,Ali Shamooni,Hendrik Nicolai,Oliver T. Stein,Andreas Kronenburg,Achim Kempf,Christian Hasse +6 more
TL;DR: In this article , the structure of a coal flame in a temporally evolving turbulent jet with flue gas recirculation is analyzed with different flamelet models considering two mixing scenarios, namely the mixing of recirculated flue gases with the other fuel or oxidizer streams.

Application of the Dynamic F-TACLES Combustion Model to a Lean Premixed Turbulent Flame
TL;DR: In this paper, Wang et al. proposed a power-low wrinkling model for a lean premixed turbulent Bunsen type flame (Matrix Burner) with dynamic and non-dynamic formulation on two different grid levels to retrieve the evolving flow and combustion properties.
Large eddy simulation of the transition process from regular to irregular shock-wave/boundary-layer interaction
TL;DR: Li et al. as discussed by the authors proposed transition criteria for the reflection of asymmetric shock waves corresponding to the detachment criterion, while in the opposite case transition from MR to RR occurs at the von Neumann condition.

The theory of homogeneous turbulence
TL;DR: In this article, the kinematics of the field of homogeneous turbulence and the universal equilibrium theory of decay of the energy-containing eddies are discussed. But the authors focus on the dynamics of decay and not on the probability distribution of u(x).
Journal ArticleDOI
Direct numerical simulation of free-surface and interfacial flow
TL;DR: In this paper, the authors consider the formation of droplet clouds or sprays that subsequently burn in combustion chambers, which is caused by interfacial instabilities, such as the Kelvin-Helmholtz instability.

Direct simulation of a turbulent boundary layer up to R sub theta = 1410
TL;DR: In this paper, the turbulent boundary layer on a flat plate, with zero pressure gradient, is simulated numerically at four stations between R sub theta = 225 and R sub tta = 1410.

DIRECT NUMERICAL SIMULATION: A Tool in Turbulence Research
Parviz Moin,Krishnan Mahesh +1 more
TL;DR: In this article, direct numerical simulation (DNS) of turbulent flows has been reviewed and the complementary nature of experiments and computations in turbulence research has been illustrated, as well as how DNS has impacted turbulence modeling and provided further insight into the structure of turbulent boundary layers.
