Abstract: To investigated the ignition and lean blow out performance of a trapped vortex combustor(TVC)test rig,abundant experiments have been employed in variety inlet conditions.The TVC used a new type evaporating tubes as fuel injection manner,with kerosene as fuel.The results of the experiment indicate that the TVC could be used to extend combustion boundary.
