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