SUPERSONIC INVISCID FLOWS WITH THREE-DIMENSIONAL INTERACTION OF SHOCK WAVES IN CORNERS FORMED BY INTERSECTING WEDGES

Results of numerical and analytical investigations of inviscid steady supersonic flows in corners formed by intersecting wedges are presented. Despite the great number of papers dealing with such flows, many features of the formation of complex systems of spatially interacting shock waves in corner configurations have not been adequately studied. Some of these problems are investigated in the present paper by consideration of the generic corner flows, which are conical and symmetric about the bisector plane of a corner. These flows are numerically calculated by solving three-dimensional steady Euler equations with a marching method. Effects of the angle of inclination of the corner surfaces to the free stream direction, sweep angle of the leading edges and the dihedral angle of the corner are discussed. Transition from regular to irregular reflection of shock waves In the corner flows considered, planar shock waves generated by corner wedges intersect and reflect at the bisector plane. Both regular reflection (RR) and irregular (IR) or Mach reflection (MR) of these shock waves are possible [1-7]. It is very important, both for theory and applications, to determine the boundaries of domains of the regular and irregular reflections. In particular, this problem for the case of conical flows in corners was considered i
