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 …

A novel approach to the description of flame transfer functions of premixed swirling flames is
presented based on a simplified analysis of the vorticity transport equation. With this model it …

This study reports on experimental investigations on isothermal and reacting swirled non-
premixed flows under varying pressure conditions. In this configuration, a central high speed …

The present experimental study reports first observations of stability, blowout, and blowoff
characteristics of ammonia–hydrogen–nitrogen fuel blend flames with varying volumetric …

Particle image velocimetry methodology results in a spatial averaging of the real velocity
field into a set of discrete measured velocities: one for each interrogation cell. In the absence …

In this contribution the three-dimensional reacting turbulent flow field of a swirl-stabilized gas
turbine model combustor is analyzed numerically. The investigated partially premixed and …

This work focuses on the numerical simulation of a gas turbine model combustor operated
near the lean extinction limit using a hybrid LES-RANS model. A broad experimental …

An experimental investigation in a sector (⁠ 20 deg⁠) of full-scale annular gas turbine
combustor is performed. The sector combustor is optically accessible for the flow and flame …

Aiming to improve the stabilization of unstable swirling turbulent premixed flames, an
actively controlled swirler and electrical hardware and control software are developed …

While the basic capability of large eddy simulation (LES) has been amply demonstrated on a
number of relatively simple academic configurations, there is still a lack of works applying …
