Outline of Final Research Achievements

Compared with the conventional detonation driven by chemical reactions, for the case of the super-high temperature detonation, such as a nuclear reaction driven detonation, the non-local energy transports (e.g., electron thermal conduction, radiation transport and transport of fusion products) play the important roles in the propagation mechanism. In the present research, I carried out the numerical simulations for the laser-driven detonation, which is one of the super-high-temperature detonation and has been experimentally and theoretically studied, and evaluated the propagation properties. Also, the initiation and propagation of the nuclear reaction driven detonation has been studied for the fast ignition laser fusion.
