| Outline of Final Research Achievements |
In this study, experimental simulation method of evaluating overpressure variation induced by a blast wave interacting with turbulent flow was developed. The blast wave was generated using a 0.51-gram power. The turbulent flow was generated with an electrical fan, duct and grid. Overpressure histories were measured using four microphones set symmetrically. A 40 % standard deviation in overpressure was obtained, thereby demonstrating spatiotemporal behavior as the result of the shock wave-turbulence interaction.
