Mostly damages in industrial accidents are resulted from explosions of combustible gases and among other combustible gases H2 has unique properties, which makes it one of the most dangerous agent.

Thus we are going to speak here about numericalmodeling of possible accidents in industry with H2

What are the tasks for CFD in safety: there is a need in better understanding andin development of complete modeling procedure with the view:

to predict accident progress and consequences
to develop efficient mitigation measures
to provide reliable data base for rules, codes and standards
to support development ofsafe hydrogen technologies
