Temperature Factor Effect on the Disturbance Propagation in the Flow past a Blunt Plate in the Interaction Regime

Supersonic viscous gas flow past the upper surface of a blunt finite-length plate is considered in the interaction regime. The temperature factor effect on the pressure disturbances initiated by mounting a wedge at the plate end, the aerothermodynamic flow characteristics, and the disturbance propagation upstream are investigated. Numerical calculations are carried out within the framework of the solution of the stationary two-dimensional Navier–Stokes equations.
