Abstract | Measurements from a rake of heat flux probes installed in a 62.2 mm diameter shock tunnel have been used to deduce the thickness of the shock tube interface and its distribution across the tube for a primary shock Mach number of 2.3. The axial thickness of the interface was between about 0.32 and 0.42 m for locations from about 2.0 to 2.5 m downstream of the diaphragm station. Axisymmetric simulations using a compressible Navier Stokes solver to model the entire shock tunnel operating at this condition show a simulated interface distributed over an axial length of about 0.20 m at 2.0 m downstream of the diaphragm, thus underestimating the measured interface length by about 37 %. The simulations indicate that the diaphragm opening process has a strong influence on the interface development within the nominally inviscid core flow region of the tube. The shape |
