Large-Eddy Simulation of turbulent flows

Large Eddy Simulation and Related Techniques, 2020
Large-Eddy Simulation (LES) of low Mach number compressible turbulent flows has been investigated. An efficient algorithm has been developed and successfully applied to two test cases such as the channel flow and cavity flow.

Large-Eddy simulation of pulsatile blood flow [PDF]

, 2009
Large-Eddy simulation (LES) is performed to study pulsatile blood flow through a 3D model of arterial stenosis. The model is chosen as a simple channel with a biological type stenosis formed on the top wall.

Numerical studies towards practical large-eddy simulation [PDF]

, 2007
Large-eddy simulation developments and validations are presented for an improved simulation of turbulent internal flows. Numerical methods are proposed according to two competing criteria: numerical qualities (precision and spectral characteristics), and

Study on lattice Boltzmann method/large eddy simulation and its application at high Reynolds number flow

Advances in Mechanical Engineering, 2015
Lattice Boltzmann method combined with large eddy simulation is developed in the article to simulate fluid flow at high Reynolds numbers. A subgrid model is used as a large eddy simulation model in the numerical simulation for high Reynolds flow.

Large Eddy Simulation of Yawed Wind Turbine Wake Deformation

Energies, 2022
Wind turbine wake redirection drawn by a yaw control has been proposed as a strategy to improve the performance of wind farms. However, the characteristics and the development of the curled wake structure deformed by the yaw action of the rotor are not ...

Large Eddy Simulation of Combustion for High-Speed Airbreathing Engines

Aerospace, 2022
Large Eddy Simulation (LES) has rapidly developed into a powerful computational methodology for fluid dynamic studies, between Reynolds-Averaged Navier–Stokes (RANS) and Direct Numerical Simulation (DNS) in both accuracy and cost.
