Numerical simulation of nano size aluminum particle-oxygen two-phase detonation is performed using two-dimensional compressible Euler equations with a two-step combustion model. The present study is conducted to investigate numerically detonation characteristics of nano-size aluminum particles. The numerical results show that the detonation cell size becomes small when the aluminum particle size decreases, but this tendency becomes quite different from the micro-size particle case. Furthermore detonation in nano-size aluminum particle-oxygen mixture propagates at the near C-J value when its size becomes smaller.
