Recent developments in numerical schemes, turbulent combustion models and the regular
increase of computing power allow Large Eddy Simulation (LES) to be applied to real …

The large-scale coherent motions in a realistic swirl fuel-injector geometry are analysed by
direct numerical simulations (DNS), proper orthogonal decomposition (POD), and linear …

Velocity fields and flame structures of a partially premixed swirl flame in a gas turbine model
combustor are measured in axial and transverse sections using simultaneous (Stereo-) PIV …

Abstract Large-Eddy Simulation (LES) has become a potent tool to investigate instabilities in
swirl flows even for complex, industrial geometries. However, the accurate prediction of …

Since lean premixed combustion allows for fuel-efficiency and low emissions, it is nowadays
state of the art in stationary gas turbines. In the long term, it is also a promising approach for …

The present paper reports on the investigation of turbulent transport and fuel mixing under
nonreacting conditions for a model gas-turbine swirl burner based on a design by …

We studied flow dynamics in a model combustion chamber using Large-eddy simulations
(LES) and Particle image velocimetry (PIV) at the Reynolds number R e of 15,000. The swirl …

To prevent flame flashback in swirl-stabilized, lean premixed combustion, a nonswirling air
jet is introduced on the central axis of the radial swirl generator. This axial injection of air …

The present experimental investigation concerns identification of stable flame regimes and
blowout limits of ammonia-hydrogen-nitrogen flames in confined coaxial swirling jet …

It is well known that the process of vortex breakdown plays an important role in establishing
the near-field aerodynamic characteristics of fuel injectors, influencing fuel/air mixing and …
