| Abstract: | In order to study the propagation characteristics of the detonation wave of the powder fuel in the atmosphere of the gaseous oxidizer and F/O mixture, the experiments and numerical calculations of the detonation of the powder fuel suspended in the gaseous atmosphere are reviewed. The critical factors which conduct influences on the wave velocity, stability, propagation mode, detailed structure and cell size of the detonation wave are concluded. Meanwhile the examples of application of the detonation engine or combustor with powder fuel are introduced. The experimental setups, combustion diagnose measurements and numerical simulation methods are summarized and analyzed in terms of the characteristics of the powder detonation. Finally, the next work to make powder fuel detonation engine more practical is estimated. |
