  Flow Stabilization in a Transonic Wind Tunnel with a Second Throat

  摘要：

  A second throat has been used to stabilize the how in the test section of an induction-driven transonic wind tunnel. Different second throat configurations were attempted by employing simple wall-fixed flaps and a centerline-fixed strut, and their efficiency based on the duration of stable test section how was examined. Generally, a longer duration of stable flow could be achieved when the tunnel was operated with a second throat than without one. Moreover, a longer run time was achieved with the wall-fixed flaps than with the center strut. The performance of the center strut was so poor that it raised concerns about the installation of the sting support, which is usually installed in the same manner as the center strut. It was also found that when the flaps were installed vertically on the sidewalls the low-momentum reentry how from the plenum chamber reduced the effectiveness of the flaps in choking the how The performance was greatly improved by repositioning the flaps horizontally and directly behind the reentry region. However, there was an upper limit to the effectiveness of the flaps in choking the how Beyond a certain injector total pressure the effective cross-sectional area of the diffuser at the injector's location was reduced by the jet, turning it into the effective throat area. The cross-sectional area at the second throat is rendered ineffective, causing the Mach number in the test section to temporarily drop.
