Abstract
Experiments are carried out to investigate the shock train in an isolator model. In one model, the wetted surfaces can be heated up to 1000 K. The tests are performed in a hypersonic shock tunnel facility at Mach 7.7 with varying total temperature. The wall temperature is varied between 300 and 1000 K. The experiments show the influence of the wall temperature on the pressure distribution in the shock train. This effect is not covered by the correlation of Waltrup and Billig. The correlation is expanded with the influence of the wall heat flux to include these effects.
