Abstract

Relations for the coefficients of transformation of disturbances to pressure oscillations for the case of long-wave disturbances of the external flow are derived from the general analytical solution of the inviscid problem of disturbance interaction with an oblique shock wave on a wedge. Numerical simulations of interaction of long-wave disturbances with a shock wave on a flat plate aligned at an angle of attack in the interval 5°–20° for a viscous flow regime are performed. Deviations of the transformation coefficients simulated for the viscous case from the inviscid analytical solution in the long-wave approximation are calculated, and corrections for viscous-inviscid interaction in the analytical solution are obtained.
