Maximum pressures vary with corner angles.

Flow patterns are visualized at different time moments.

Abstract

Cumulation of shock snd detonation waves was considered. Computations were carried out by use of second-order central-difference scheme. Cumulation of waves in cone region with scales of 1 meter was studied. Pictures of flow in shock and detonation waves during different time moments were obtained as well as time dependences and maximum pressures for different corner angles.
