Numerical simulations were performed with a parallel computer to solve for the behaviour of the three-dimensional gas-solid two-phase detonation. The numerical method is a second-order modified Harten-Yee TVD upwind scheme and time integration uses a first order Euler integration. A two-step chemical reaction model represents the reaction of constarch-particles and oxygen. The numerical results show that a periodic two-headed detonation appears with a three-dimensional propagation mechaism before and after a triple point collisions. A comparison between the numerical and experimental results reveals that detonation velocity of numerical results agrees well with that of experimental results.
