-premixed double concentric swirl-flame burner was used. Noise spectra were determined experimentally for the non-premixed swirl flame … coherence between different microphone pairs was also carried out to determine the acoustic behavior of a swirl stabilized …

has led to the application of RANS-based models to more and more complex flow problems and permitted the use of LES …-based models where previously not possible. The following article reviews the development of CFD as applied by the wind energy …

computational fluid dynamics (CFD) software CFdesign 2010. A validation study consisting of steady and rotating simulations was … conducted using a Savonius rotor and good agreement was obtained with experimental data. Steady two-dimensional CFD simulations … three-dimensional CFD simulations were conducted at several tip speed ratios with a freestream speed of 6 m/s. The predicted …

A novel computational fluid dynamics (CFD) model is presented for the study of the scavenging process and convective … resolved 12° sector, corresponding to one scavenge port, with cyclic boundaries in the tangential direction. The CFD model is … solution of the Reynolds-Averaged Navier–Stokes (RANS) equations subject to boundary conditions obtained through experiments …

Generators (WTGs). We have developed a CFD model for unsteady flow called Research Institute for Applied Mechanics, Kyushu … University, COMputational Prediction of Airflow over Complex Terrain (RIAM-COMPACT^®). The RIAM-COMPACT^® CFD … model is based on Large-Eddy Simulation (LES) technique. The computational domain of RIAM-COMPACT^® can extend …
