Gas-explosion events in the private or industrial field are usually followed by a technical analysis of the factors that led to their generation. In this respect, INCD INSEMEX Petroşani is accredited for conducting the technical expertise and for the elaboration of the Expertise Report. Starting with on-site findings and sampling, research continues at INCD INSEMEX laboratories, grouped on areas of interest in case management (electrical, ventilation, chemical, pyrotechnics, etc.). Determining the causes of the event implicitly involves establishing the probable source of initiation of the explosive mixture, after discovering the fuel gas source and analyzing how the mixture was formed. Due to the geometric complexity of the space in which the explosion occurred, incident, reflected or compound shock waves generated by explosion can create a footprint of the event that questions the location of the source of initiation. Depending on the possible sources found in the field, the INSEMEX Laboratory of Computational Simulations performs analyzes based on finite elements and finite volumes methods. The elements taken into account in the computational simulations concern both the geometry of the space, the nature of the combustible gas leakage, the dispersion of the gas, and the resulting thermal and mechanical effects.
