In three dimensions overpressure is generated not by the rate of energy addition but by the first time derivative of the rate. Because of this, deflagrative combustion of edge-ignited clouds produces markedly less overpressure than central, spherical ignition. Examples are presented for three nonspherical cloud and igniter geometries. The implication is that even high velocity, subsonic combustion waves cannot produce damaging blast waves and that some type of supersonic combustion or massive flame acceleration is required if a damaging blast wave is to be produced.Read More
