Experimental Study of Ignition Characteristics in Oblique-Injected Annular Combustors Using a Pre-Chamber Ignition System

Aerospace Research Communications
In this work, a pre-chamber ignition system is used to initiate the ignition in a premixed oblique-injected annular combustor. Although the introduction of the oblique-injecting burner in the gas turbine improved the gyratory flow motion and flow ...
