Abstract: The interaction of different types of long-wavelength perturbations of a supersonic incident flow around a wedge with an arising shock wave is simulated numerically. The results of parametric calculations are compared with the data of the linear theory for the interaction of perturbations with a shock wave in the absence of a body. Data on the structure of pressure fluctuations behind the shock wave on the wedge and data on the coefficients of transformation of external perturbations represented in the form of analytical dependences on the angle of inclination of the shock wave, the angle of propagation of external perturbations, and the incident Mach number are obtained.
