Simulation modelling of the deflagration behaviour

Abstract

Mitigation through ignition and venting prevents potential detonation situations, but the resulting deflagration burn can still pose a threat to containment structures. The purpose of this research is to understand the general behaviour of vented deflagration using simulation. This paper discusses simulation modelling for the deflagration process in large volumes. The simulation is used to estimate pressure development and visualize flame growth during a deflagration. The simulation model is simple and efficient for the complicated deflagration process. It can be used in real time with design changes. © Springer-Verlag Berlin Heidelberg 2010.
