| Abstract: | The interaction between a plane normal shock and ellipsoidal regions of elevated or lowered density in an ideal perfect gas
is investigated. Qualitatively different interaction patterns, regular and irregular, are found to exist. It is noted that
as a result of the irregular interaction a complicated flow incorporating refracted shocks, tangential discontinuities, and
vortices is formed. The effect of shock cumulation on the axis of symmetry occurring outside or inside a gas inhomogeneity
of both lowered and elevated density is studied. The qualitative and quantitative influence of the inhomogeneity shape on
the cumulation effect is investigated. |
