6. Conclusion and outlook
Gas explosions are complex phenomena, highly unpredictable in terms of both their probability of occurrence and the effects they can produce.
Research over the last few decades has led to major advances both in understanding the various factors influencing their intensity, and in software modeling. It is now possible to use a variety of tools to model macroscopically the effects of an explosion in the open air, in order to assess their impact. The integration of a probabilistic approach in design studies now makes it possible to limit conservatism and take a more global view of the risk associated with explosions, particularly when it comes to dimensioning.
However, there are still a number of difficulties to be overcome in order to model the combustion process more accurately at the microscopic scale, particularly turbulence and the interaction...
