Development of a 3-D Blast Overpressure Modeling Capability Utilizing Fluent•A blast waveis the pressure and flow resulting from the deposition of a large amount of energy in a small very localized volume.
–Flow field can be approximated as a lead shock wave, followed by a 'self-similar' subsonic flow field
•Shock waves cause a virtually instantaneous jump in pressure at the shock front
•The combination of the pressure jump (called the overpressure) and the dynamic pressure causes blast damage
•It is necessary to understand blast wave to
–Estimate the damage that will result from an explosion
–To devise mechanisms for mitigating the blast
