| description | The invention relates to an inward turning type air inlet channel flow control method based on MVG, and belongs to the technical field of air suction type engine design. In the scheme, the MVG is arranged at the reasonable position, it is only needed that the MVG direction is the same as the streamline direction obtained through streamline tracking, the structure is simple, the control effect is remarkable, additional flow losses are avoided, secondary flow deviating from the main flow direction can be used for generating vortexes opposite to the direction of streamwise vortexes generated in an air inlet channel; the purpose of inhibiting and eliminating the streamwise vortexes is achieved through neutralization of vorticity; and meanwhile, according to the scheme, when only the bottom plate MVG acts, the streamwise vortexes in the flow field can be effectively restrained, and the influence on throat airflow can be further reduced. After the top plate MVG is added, the MVG with a bottom plate controls the vor |
