“…Gaseous detonation technology has a good application prospect in engine [2][3][4][5][6]. Most of the experimental studies and numerical simulation in the gaseous detonation wave focus on cell structure evolution and the influence of initial conditions in a straight pipe [7][8][9][10][11][12][13][14].…”

The influence of different bend curvatures on the detonation wave propagation was analyzed by an advanced numerical simulation system. The mechanism of propagation properties is revealed by cellular structure, internal and external boundary pressure distribution, propagation process of detonation wave and chemical reaction. The cellular structure and detonation wave front of bend with different curvature are very different. The simulation results show that the detonation wave with regular cell structure propagating through the curved parts induces detonation cell size increased by diffraction near the inner wall while detonation reflected on the bottom surface resulting in decrease of cell size. Detonation wave was affected by the rarefaction wave and compression wave in the bent pipe. The pressure distribution of the bend shows that the peak pressure in the 450 curvature is the largest, which should be paid more attention in industrial design. The chemical reaction could indicate the propagation characteristics of detonation wave, and different propagation characteristics have different profiles of chemical components.

“…In nature, the multidimensionality of detona tion manifests itself in the cellular structure and in the spin. The cellular and spin detonations are formed due to instability of the burning zone behind the head shock wave, due to which small perturbations increase, and periodic spatial flows arise with trans verse waves in the flow behind the head shock and with breaks of its front [1][2][3][4]. Previously, various authors investigated mainly numerically the formation of the 2D cellular detonation in the channels.…”
