Abstract: The physical aspects of nonuniqueness for the shockwave structures arising in super- and hypersonic flows are considered. The thermodynamic conditions specifying the regions of double solution are analyzed. Possible scripts for variation of gas dynamic flow pictures near the boundary of "Mach/regular reflection" transition are investigated.

Keywords: shockwave structures, super- and hypersonic flows, thermodynamic conditions, gasdynamic patterns, boundary transitions.
