Large Eddy Simulation of the meandering of a wind turbine wake with stochastically generated boundary conditions
TL;DR: In this article, the authors proposed a method to generate and apply synthetic turbulent velocity series as boundary conditions in a Large Eddy Simulation of an actuator disk in a flow with realistic turbulence characteristics.

Application of the Evolution-Variable Manifold Approach to Cavity-Stabilized Ethylene Combustion
TL;DR: In this article, the LES-EVM approach is used for the simulation of turbulent combustion of hydrocarbons in high-speed flows, including those dominated by ignition delay, and encompass regions of thin reaction fronts as well as distributed reaction zones.

Loss Analysis of Unsteady Turbomachinery Flows Based on the Mechanical Work Potential
John Leggett,Edward S. Richardson,Stephan Priebe,Aamir Shabbir,Vittorio Michelassi,Richard D. Sandberg +5 more
TL;DR: Miller et al. as discussed by the authors developed the practical application of mechanical work potential loss analysis, providing the mathematical formulations necessary to perform loss analysis using practical Reynolds-Averaged Navier-Stokes (RANS) or Large Eddy Simulations (LES).

Large Eddy Simulation of flame stabilisation dynamics and vortex control in a lifted H2/N2 jet flame
TL;DR: In this article, an academic lifted jet flame and Large Eddy Simulation (LES) is used to capture the flame and auto-ignition dynamics, and the vortex dynamics linked to these fluctuations are analyzed and it is found that small scale coherent structures play a vital role in the autoignition process.

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.
