Due to the high Reynolds numbers together with the complex turbulent motions in
turbomachinery, selecting a proper turbulence-modeling method is of vital significance in …

The effect of changes in fuel calorific value on combustion was investigated on a single
standard Siemens SGT-300 7.9 MW dry low emission (DLE) combustor in a high pressure …

The self-induced thermoacoustic instabilities in partially premixed combustors remain a
significant challenge which has received a limited research attention. This numerical work …

This study characterizes the central recirculation zones formed under combustion
conditions, with natural gas as fuel with different geometries and degrees of premixing using …

Double helical precessing vortex core (PVC) and its interaction with premixed propane
flame in a swirl-stabilized burner is studied numerically. The model burner is operated under …

The present paper compares the flow structure and flame dynamics during combustion of
methane and syngas in a model gas-turbine swirl burner. The burner is based on a design …

The use of an innovative, intelligent control algorithm applied to the Siemens SGT-300 DLE
engine is described. The algorithm ensures stable operation and minimises emissions over …

This paper describes numerical predictions of the forced heat release responses of a lean
premixed bluff-body stabilized ethylene/air flame, using the hybrid Stress-Blended Eddy …

This work numerically investigates longitudinal and azimuthal thermo-acoustic instabilities in
the swirl-stabilised can-type industrial SGT-100 gas turbine combustor operated at elevated …

This thesis numerically predicts thermoacoustic instability in two typical gas turbine
combustors. Incompressible large eddy simulation (LES) is used as the main numerical tool …
