| Abstract: | Various regimes of interaction of an axisymmetric supersonic underexpanded jet of a gas with both a finite and an infinite
planar target are studied numcrically. The model of an idcal perfect gas and one variant of Godunov's highly accurate scheme
are used. The calculated and experimental frequency spectra of pressure oscillations in the center of the target are compared:
their good agreement is obscrved.
