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 ...

Numerical investigation on turbulent flame jet characteristics of ultra-lean H2/air ignited by pre-chamber enrichment strategy

Energy Conversion and Management: X
Pre-chamber enrichment for igniting ultra-lean premixed H2/air is an effective strategy for achieving ultra-low emission and improved fuel economy. This study employed a three-dimensional numerical simulation based on a constant volume combustion chamber
