  • In order to study on the control of the wing-body juncture horseshoe vortex utilizing Venturi tube,a typical wing-body junction region was presented.In order to conduct the control of horseshoe vortex,a wing with a slot placed upstream in the flat plate and a Venturi tube mounted on the other side of the plate was established.Because of the Venturi principle,when the flow passed over the throat,the slot acted as a quality injector.Numerical simulation was conducted to investigate turbulent junction flow with different positions of the slot.The results show that the horseshoe vortex can be controlled well,and furthermore eliminated completely horseshoe vortex,through the modification of the slot position relative to the wing.The proposed method can utilize potential energy,and does not consume any additional power.Therefore,it is a kind of passive control method with a great practical application prospect.The approach of the control of junction flows based on Venturi principle presented in this paper is promising in the engineering application since it is very simple and applicable.
