Abstract
The bubbling dynamic behavior and acoustic radiation characteristics originating from the combustion of pyrotechnic mixtures of KClO 4/Mg-50 %Al alloy, and with different charge density such as 1500 kg/m 3, 1600 kg/m 3, 1700 kg/m 3 and 1800 kg/m 3, were studied by theoretical calculation and experiment. The experimental and numerical correlation results were in a good agreement with each other. Then, the bubbling dynamic behaviors were compared, the results revealed that with the increase of the charge density of each 100 kg/ m 3, the volume of the bubbles, the volume change acceleration and the sound pressure level average increased by 1.78 times, 2.28 times and 1.15 times respectively.
