Experimental study of stratified swirl flame dynamics in a model gas turbine combustor

The flame structure and dynamic response of stratified swirl flames are investigated using a stratified premixed swirl burner. The change of swirl intensity is achieved by swirlers with different swirl angles. Stratification of the flow and mixtures is established by varying the bulk air flow rates...
