Blast Mitigation Strategies in Marine Composite and Sandwich Structures

Abstract

Shock wave attenuation has been studied by using rough walls. The roughness at the walls is added by placing grooves. The experimental study employed a shock tube and non-electrical (NONEL) tube placed above the surface. The shock tube experiments were performed for driver gas (air) pressures of 4, 8 and 12 bar and atmospheric pressure within the driven section, giving theoretical Mach number of 1.34, 1.54 and 1.66, respectively. In the NONEL tube experiments, detonation initiates inside the NONEL tube, due to the reactants deposited on its internal surface, producing a blast wave and consequent products of combustion. High-speed schlieren photography and pressure measurements were employed to visualize and quantify the flow field.
