Abstract
The detonation is a combustion wave that propagates at the supersonic speed in a stationary reactive mixture in the form that consists of a precursor shock wave and a reaction region induced by the shock. In this study, behavior of the detonation that propagates in a channel with a right corner is calculated by two-dimensional analysis and three-dimensional analysis. The results of this study are as follows: Results due to a change of coordinate system occur no large difference. Theory of Skews gives a similar results in the detonation. When the detonation propagates into a channel with a right corner, the detonation configurations collapse by the Prandtl-Meyer expansion. But its configuration re-generates by interference with the reflected wave and collisions with the wall. When two-dimensional behavior of the detonation is calculated, no large difference are shown on results of the two-dimensional analysis and three-dimensional analysis in the case of the aspect ratio 5.
