Multienergy method, vapor cloud

The multienergy method is based on the concept that, if detonation of unconflned parts of a vapor cloud can be ruled out, strong blast is generated only by those cloud portions which bum under intensely turbulent conditions. Such cloud portions include, for instance, intensely turbulent fuel-air jets resulting from a high-pressure... 

The multienergy method applies only if detonation of unconfined parts of a vapor cloud can be ruled out. If so, the explosive potential of a vapor cloud is determined primarily by the blast-generative properties of the environment in which the vapor is released and disperses. Consequently, a vapor cloud explosion can be regarded as a number of subexplosions. Therefore, the first step in applying the multienergy method in vapor cloud explosion hazard assessment is...
