N2 - A double pulse pneumatic spray system was designed based on the requirements of multiphase explosion expriments. Water was employed to study the spray characteristics of the system. The two phase flow pattern in delivery pipe, the gas-liquid mixing process of spray room, the angle of spray, the Sauter mean diameter D32 and the particle size distribution were measured via digital image processing technology and laser Doppler methods, respectively. The experimental results prove that the annular two-phase flow is the main flow structure in the gas and liquid delivery pipe when the initial pressure is in the range of 0.8-3.3 MPa, the water is between 50-500 mL and the spray duration is fixed at 450 ms. In the meantime, double pulse pneumatic spray was found in gas and liquid mixing process, corresponding to the spray angle between 138°-170° and the mean D32 of 61 μm at 500 ms, respectively.
