The behavior of micro explosive charge underwater explosion near a rigid wall

The interactions between an underwater explosion and underwater structures is a research topic related to understanding strong impulsive forces for disaster preparation and prevention. This study is a part of series studying the behavior of underwater explosion bubbles near different boundaries and structures because understanding the boundary phases and the pulsation of bubbles could be a useful predictive tool. Micro explosive underwater explosions were conducted by detonating a very small amount of silver azide; the time evolution and attenuation of effects from the explosion were studied. Both numerical and experimental data were acquired and compared for underwater shock waves, gas bubbles and overpressures caused by the micro explosions.
