Quiet chevron/tab exhaust eductor system

摘要

The present invention provides a means for inducing (educting) a "passive" secondary flow stream using an exhaust eductor system including a primary exhaust nozzle designed to transport an active flow stream and a plurality of tabs extending from a rear perimeter of the primary exhaust nozzle. Each of the tabs is designed to be bent at an angle in relation to the primary exhaust nozzle. An exhaust mixing duct is positioned around the primary exhaust nozzle that is designed to transport a passive flow stream to the active flow stream where the plurality of tabs create a streamwise vorticity to enhance the mixing of the active flow stream and the passive flow stream.
