Abstract

The flame acceleration in the presence of complex geometry is an important issue as far as explosions within industrial environments are concerned. A high level of confinement due to obstacle congestion often characterises chemical plants handling flammable gases. In the case of gas explosion, this feature leads to strong acceleration of the flame and the generation of very destructive blast waves. Empirical methods such as the Multi-Energy method are commonly used in order to quantify the possible damage of explosions. Computational fluid dynamics (CFD) is an emerging technique to predict the consequences of gas explosion and it is often considered a powerful and accurate tool to obtain detailed analyses of the flame propagation. However,
