Condensed-phase explosion described

As discussed in Section 3.2.1, other explosion events can occur that impact process plant buildings, including condensed-phase explosions, uncontrolled chemical reactions, PV ruptures, and BLEVEs. Appendix A and Reference 5 describe the information needed and the methods available for calculating blast parameters from these events. 

Dr Gustav Schweikert of Bad Godesberg, described in Explosivstoffe 3, 197-200 (1955) and 4, 10-14 (1956) a theory of detonation of condensed-phase explosives, which is based on the assumption that such.detonations follow essentially the same basic laws as the combustion of colloidal propellants, and can be comprehended thru the same molecular and reaction-kinetic theories... 

The calculated equivalent amount of TNT energy can now be used to estimate shock wave effects. The analogy of the explosion of a container of pressurized gas to a condensed phase point source explosion of TNT is not appropriate in the near field since the vessel is not a point source. Prugh (1988) suggests a correction method using a virtual distance from an explosion center based on work by Baker et al. (1983) and Petes (1971). This method is described below.
