WebBlast wave. In fluid dynamics, a blast wave is the increased pressure and flow resulting from the deposition of a large amount of energy in a small, very localised volume. The flow field can be approximated as a lead shock wave, followed by a self-similar subsonic flow field. In simpler terms, a blast wave is an area of pressure expanding ... WebThe simulations have reproduced well experimental parameters such as blast wave decay, overpressure dynamics at di¨erent locations, including the timing of the blast wave arrival, as well as reball shape and size. One of the advantages of the CFD model with radiation is the ability to calculate hazard distance by thermal dose. 展开
