Differentiated routes for the simulation of the consequences of explosions
Tecniche per la simulazione delle esplosioni e calcolo degli sfiati
Résumé
Explosion venting is a well accepted method for mitigating dust explosions. A number of tests have proven the efficiency of this protection means and a number of correlations have been established on this basis. Although the latter are based on reasonable physical grounds, comparison with realistic experiments shows that the explosion overpressures might be overpredicted but also sometimes underpredicted. Along the last ten years, significant effort has been devoted to try to understand the reasons for this and the initial turbulence of the cloud has been pointed as being a major factor. A technique is proposed to take this into account
