Experimental research on dynamic concentration distribution of FAE solid fuel

The appropriate concentration of fuel cloud is a precondition of the detonation reaction. Because of the complex mechanism of the dispersing process and the lack of the testing devices, the special experimental research on the dynamic concentration distribution of fuel is still very lack. An array experimental system based on the concentration measurement microsystem CMM-1 is established to detect the concentration of the fuel cloud generated by a scaled-down dispersing device; the temporal and spatial variation curves of the fuel concentration are obtained, and the change law of the concentration peak is established. The experimental results show that the dynamic concentration distribution of fuel can be obtained using the experiment system and the proposed method.
