Gas detonation in 2H2/O2 mixture initiated by high explosive AgN3 is numerically studied in this paper. Fully 3D Navier-Stokes equations are solved by upper wind TVD scheme. Self-similar solution is used to simulate ignition of AgN3 by neglecting its detailed chemistry. The flow field near explosion center must be simplified because of the high temperature. Chemical source term is treated by point-implicit method to avoid the stiffness. 12species/23steps model is used to describe the chemistry of 2H2/O2 mixture. Contours of pressure, temperature, and species mass fraction are obtained. The results indicate that the self-sustained propagating spherical detonation wave can be generated, and DDT process is shortened for large shock Mach number Ms. The detonation wave reflects as shock waves on side and end walls. For different Ms (2.0∼3.5), the parameters of steady detonation are the same but flow field near the explosion center is different. The computed detonation parameters are less than those got from C-J theory.
