Study on Process of Multi-Phase Suspension Flow Cloud Combustion and Detonation

The experiments of aluminum powder-nitro methane-air mixture multi-phase suspension flow cloud combustion and detonation was conducted by means of a 30 m long, 0.2 m inner diameter large horizontal tube in the paper. The history of pressure signal along the tube was detected under the condition of weak ignition. It could be concluded that the regulation of explosion overpressure peak value, explosion velocity along the tube and shock wave induced by flame acceleration. It revealed inherent law of gas-solid-liquid multi-phase cloud detonation propagation along the tube.
