Abstract:
Ignition dynamics in an annular combustor with turbine guide vanes was experimentally studied on a TurboCombo platform.High-speed cameras were used to observe and record the light-round sequence and the interaction between flame and turbine guide vanes.The light-round sequence and the light-round time were compared between the annular combustor with or without turbine guide vanes at different equivalence ratios,thermal powers and bulk velocities.The experimental results indicate that the light-round sequences are similar in the two configurations,but the annular combustor with turbine guide vanes features shorter light-round time in the same condition.With the turbulent wrinkling and burnt gas expansion effect considered,the circumferential flame speed was estimated,which fitted the experimental results well at a larger Reynolds number.
