Vapor cloud explosion analysis

Authors


Abstract

This paper introduces a new method (now commonly referred to as the Baker-Strehlow Method) for estimating pressure and impulse generated by vapor cloud explosions. Strehlow's blast curves and concepts from the Multi-Energy method for determination of explosion energy are applied in this technique. New correlations for maximum flame speed based on obstacle density, fuel reactivity, and cloud confinement allow selection of the appropriate blast curve. Application of these correlations removes much of the subjectivity present in existing explosion estimates.
