DESC is a simulator of Computational Fluid Dynamics (CFD) of dust explosions, developed by a consortium of 11 participants in a project of the European Community. DESC allows to simulate evolution of dust explosion in complex geometries and to assess their expected effects.
FLACS is an advanced tool for the modelling of ventilation, gas dispersion, vapour cloud explosions and blast in complex process areas. FLACS is used for the quantification and management of explosion risks in the offshore petroleum industry and onshore chemical industries.
The approach to fire safety through the Fire Safety Engineering (FSE) can essentially be assumed as the application of principles of science and engineering to the protection of people, property and environment to allow quantitative risk assessments and optimize the necessary risk reduction.
The Fire Dynamics Simulator (FDS) is a model developed by NIST (National Institute of Standards and Technology, USA) that simulates the fire and predicts the effects.
FDS allows modelling of the fire from a database of standard materials, but the user can introduce also new materials according to the physical-chemical characteristics and to the experimental data of fire. FDS is able to provide as output data values of all variables, scalar and vector, calculated in each of the cells of the domain, useful for understanding phenomena and analyse effects (concentrations of species, distribution of temperature/pressure /velocity/smoke, visibility, etc.)
