A class of transport and dispersion model which assumes that the distribution of pollutant concentration has a Gaussian or normal shape [e.g., exp(-y2/2σy 2), where y is the lateral crosswind distance from the center of the plume or puff and σy is the lateral dispersion component].
A detonation that periodically fails and reinitiates during propagation. This type of detonation is typically observed in near-limit mixtures. Since it reinitiates via DDT, a galloping detonation is periodically overdriven and results in large overpressures at periodic distances along a pipe.
The burning velocity is the rate of flame propagation relative to unburned gas ahead of the flame front. The fundamental burning velocity is the burning velocity of a laminar flame under stated conditions of composition, temperature and pressure in the unburned gas. The reported Su is usually the...
