As an active flow field control technology, reverse jet and rectifier cone can significantly affect the flow field around the high-speed aircraft and reduce the drag and heat of high-speed aircraft to a certain extent.
In this paper, the CFD numerical method is used to simulate and analyze the flow around the bluff body front rectifier cone and the reverse jet interference flow field.
Further considering the combination of the two, the flow field structure around the bluff body under the combination of rectifying cone and reverse jet flow was simulated.
Research shows, for the flow field of a single reverse jet, the pressure ratio of the reverse jet to the main flow has a significant effect on the drag reduction performance.
With the change of the pressure ratio of the jet to the main flow, two modes of long jet and short jet will appear.
The structure of the short jet modal flow field is relatively stable.
However, with the increase of attack angle, the shear layer of free flow will attach to the shock wave and form hot spot, which is a great threat to high-speed aircraft.
When the rectifier cone and the reverse jet are combined, within a certain angle of attack, the wall will not form a reattachment shock wave.
The area behind the bow shock and in front of the aircraft head is a free-state zone, which has a good cooling effect on the aircraft head.
At the same time, the static pressure on the wall is reduced, which has a very good drag reduction effect.
