Existing LES methods face three basic problems: a huge variety of LES models are currently applied, dynamic LES methods are either very expensive or have to be combined with ow-dependent empirical stabilization techniques, and the cost of LES for wall-bounded ow simulations are way too high for most applications. Solutions for these three problems can be developed by deriving non-dynamic, dynam...

The synthetic turbulence generator (STG) lies at the interface of Reynolds averaged Navier–Stokes (RANS) simulation and large-eddy (LES). This paper presents an STG for multiple-relaxation-time lattice Boltzmann method (LBM) framework high friction numbers, with consideration near-wall modeling. Reichardt wall law, in combination a force-based method, is used to model field. wall-modeled LES re...

Aerodynamic performances may be optimised by the appropriate tuning of Active Flow Control (AFC) parameters. For first time, we couple Genetic Algorithms (GA) with an unsteady Reynolds-Averaged Navier-Stokes (RANS) solver using Spalart-Allmaras (SA) turbulence model to maximise lift and aerodynamic efficiency airfoil in stall conditions [1], then validate resulting set optimal Synthetic Jet Act...

Behavior of unconfined transverse jets has been studied extensively, but little work is reported on the flow characteristics of confined transverse jets. The latter has been numerically investigated using a number of RANS codes. The computational results obtained from these codes have been evaluated against the existing experimental data, and an LES results reported in the literature. Furthermo...

Reynolds-averaged Navier-Stokes (RANS) is one of the most cost-efficient approaches to simulate wind-farm-atmosphere interactions. However, applicability RANS-based methods always limited by accuracy turbulence closure models, which introduce various uncertainties into models. In this study, we estimate model-form in RANS simulations wind farms. For purpose, compare different models a large-edd...
