Abstract: Results of numerical simulations of the evolution of disturbances in a hypersonic shock layer on a flat plate at high Mach numbers ($\mathrm{M}_\infty=21$) and moderate Reynolds numbers $(\operatorname{Re}_L=1,44\cdot10^5)$ are analyzed by an adapted method of bispectral analysis. All basic types of nonlinear interactions are obtained. The calculated results are compared with experimental data.

Keywords: hypersonic flows, shock layer, receptivity, direct numerical simulation, experiment, bispectral analysis.
