Author(s): Constantin Enache   Costin-Åžerban Niculae   Alin-Constantin Sava   

Abstract: The purpose of this article is to analyze the experimental results obtained during tests aimed at initiating a potentially explosive atmosphere using a high explosive. The detonation in open air of a quantity of TNT was carried out by numerical simulation (using the software product ANSYS AUTODYN). The results were compared with those obtained experimentally. The atmospheres achieved by the release of a fuel in the air may become explosive if various conditions are satisfied: the homogeneity of the mixture, temperature, confinement, etc.

Keywords: explosive atmosphere, confined space, shockwave front overpressure
