Effect of Experimental Conditions on the Experimental Results of Underwater Explosion

In order to obtain information about the influence of experimental conditions on the results of underwater explosion, the relationships between measure position, explosion depth and explosion parameters, which contain shock overpressure, shock wave energy per unit mass, bubble pulsation period and bubble energy per mass, were studied by experiments. The results show that the peak pressure of shock wave and shock wave energy per unit mass decrease with the increment of distance between measuring position and explosive sample, the bubble pulsation period increases and bubble energy per mass decreases with the increasing of the explosion depth. The distance between the measuring position and explosion position are at least greater than twice of the bubble radius, and the explosion depth should be 1/3 to 3/4 of the tank depth.
