Estimate of blast wave properties
Abstract
Correlation and TNT-equivalent models for UVCE blast wave properties are reviewed, and a model which estimates blast parameters from information on the cloud and its location and uses these parameters to evaluate damage is presented. The prediction model is based on calculations for an ideal, homogeneous, hemispherical, centrally ignited vapor cloud. In case of a deflagration an energy release rate function, equivalent to a certain flame path, is assumed. The results of these calculations (peak pressures as a function of distance) are used together with data for a detonating cloud. The positive phase duration is derived from separate calculations. The method estimates maximum effect, and it is not possible to predict when little or no blast will be generated.
