Semi-free jet laboratory and wind tunnel having the same

The invention discloses a semi-free jet laboratory and a wind tunnel having the same, and the semi-free jet laboratory is used to connect the nozzle output of a nozzle, is in the shape of a hollow tube, and comprises an upper laboratory wall surface and a lower laboratory wall surface that are oppositely arranged up and down, and two side laboratory wall surfaces vertically connected to the upperlaboratory wall surface and the lower laboratory wall surface, respectively, wherein the upper laboratory wall surface is a flat wall surface and is used to be in seamless joint with the nozzle outletand in smooth transition connection with the upper nozzle wall surface at the nozzle outlet, so as to prevent the air flow from forming shock wave on the upper laboratory wall surface; the side laboratory wall surfaces are flat wall surfaces and are used to be in seamless joint with the nozzle outlet and in smooth transition connection with the side nozzle wall surface at the nozzle outlet; and the a pod is formed at the
