Book Description
A new concept for creating turbulence in a wind tunnel was investigated. This concept involves the use of an array of jets to drive an open-circuit wind tunnel on the ejector principle, with the turbulence being created by the shear resulting from the difference in the velocities of the primary air and the entrained flow. A scale model tunnel was constructed, and the flow velocities obtained in it were compared with the predictions of simple ejector theory. Through the control of the velocities of the individual jets in the array, both uniform and shear flows were created, and the turbulence produced in each type of flow was studied. The concept was found to be a successful one, in that useful turbulence can be produced in both the uniform and shear flows. A fairly large range of both scales and intensities of turbulence was achieved. In addition, the results show that flow profiles in a tunnel of this type could be tailored to simulate those of any portion of a boundary layer through the control of the individual jet velocities. The effectiveness of a variable-angle diffuser at the downstream end of the tunnel in controlling mean flow velocities and turbulence characteristics was also investigated. (Author).
