Abstract Four different formation processes of spinning detonation in a narrow square tube are investigated by three-dimensional parallel simulations. High-resolution simulations are performed with a Riemann solver of the HLLC-type, high-order, parallel AMR reactive flow code. The simulations clearly show that the detonation structure transforms from rectangular and diagonal modes into spinning mode respectively during the propagation processes. Transverse wave dynamic and periodic oscillation of the front plays a significant role in the spinning detonations' formation.
