A detonation wave is a chemical reaction wave propagating at the velocity of a shock wave along the explosive charge. There is great demand for a detonation model that can accurately simulate the detonation process, which would provide a theoretical basis for highly effi- cient military destruction, the initiation of an atomic bomb, and calculations relating to the supernova SN Ia explosion. Detonation is com- plicated in that it involves mechanics, chemistry and thermodynamics simultaneously. The detonation product particles move mul- ti-dimensionally, and there are transport effects, such as friction, diffusion and heat transfer, between particles. Because of the difficulty of simulating such complex configurations, classical detonation theory, which employs the ZND model, neglects the transport effects and simplifies detonation as one-dimensional movement. However, experiments have shown that the complex movement and transport effects play important roles in detonation and should be taken into account.
