We investigate spinning detonations propagating in a square tube using numerical simulations based on three-dimensional compressible Euler equations and the two-step-reaction model proposed by Korobeinikov et al. The dynamics of the simulation results is used to understand how spinning detonations propagate. The track angles calculated from soot-track images of the square-tube walls a... https://www.spidertattooz.com/Cirque-Colors-Nail-Polish-Hygge-0-37-oz-p32304/
