Modelling of premixed combustion in a gas turbine [PDF]
Three steady state combustion models, two turbulence models and a model for tK'6 prediction of NO., were implemented and investigated on a simple backward facing step experiment as well as an experimental lean prevaporised premixed (LPP) combustor ...

Experimental Characterisation of Swirl Stabilized Annular Stratified Flames [PDF]
A burner for investigating lean stratified premixed flames propagating in intense isotropic turbulence has been developed. Lean pre-mixtures of methane at different equivalence ratios are divided between two concentric co-flows to obtain annular ...

An algorithm for LES of premixed compressible flows using the Conditional Moment Closure model [PDF]
A novel numerical method has been developed to couple a recent high order accurate fully compressible upwind method with the Conditional Moment Closure combustion model. The governing equations, turbulence modelling and numerical methods are presented

LES evaluation of the effects of equivalence ratio fluctuations on the dynamic flame response in a real gas turbine combustion chamber [PDF]
Large Eddy Simulations (LES) of a lean swirl-stabilized gas turbine burner are used to analyze mechanisms triggering combustion instabilities. To separately study the effect of velocity and equivalence ratio fluctuations, two LES of the same geometry are

Prediction of CO emission from partially-premixed gas cooker
Prediction of CO emission from gas cookers is the basis of decision on gas sources introduction, especially when introducing different gases into gas distribution networks has become a common practice to ensure supply reliability and flexibility nowadays.

Non-linearities in the thermoacoustic response of a premixed swirl burner [PDF]
PhDLean premixed combustion remains one of the simplest and most effective methods of reducing NOx emissions in industrial gas turbines. Lean premixed flames are however prone to an undesirable side effect known as combustion instability, reducing ...
