Unsteady Transonic Supersonic Flow Over Suddenly Inserted Bodies

  • Conference paper
Symposium Transsonicum II

Summary

If in a parallel transonic supersonic flow a source distribution is instantaneously inserted, a shock wave developes at the tip of the generated profile. Usually this shock wave detaches and moves upstream to a position which belongs to the steady state solution.

This flow field has been investigated in a transonic wind tunnel and in a shock tube for the two-dimensional and the axisymmetric case. The experimental results for the time dependent stand-off distance of the shock wave are compared with theoretical considerations. For moderate stand-off distances the agreement between theory and experiment is very good.

Further it was of interest to find out whether the “freezing” of the transonic flow is saved behind the moving shock wave, -as this is a basic assumption of the theory. The experiments have proved this.
