Infrared detector technologies pose a serious threat to the survivability of modern military aircraft with wide use of turbofan engines. Based on the air tab mixing enhancement technique with active flow control, experimental and numerical study was carried out on the application and mixing efficiency of air tab in multi-channel turbofan nozzle, and explored the use and control of mixing to effectively reduce the temperature of the jet to inhibit infrared radiation and meet the demand of the aircraft stealth performance. Experimental results of the model of mixing enhancement with air tab were analyzed, and verified the feasibility of the study method by comparing the experimental and numerical results. The verified numerical results show that the air tab can improve the thermal mixing efficiency of the nozzle from about 0.17 to over 0.3, and the high temperature jet core area downstream of the nozzle is reduced by more than 30%. Well mixing performance is achieved with almost no total pressure and thrust loss from mixing.
