FLACS is the industry standard for CFD explosion modelling and one of the best validated tools for modelling flammable and toxic releases in the technical safety context. FLACS is now available in Vietnam through SEN.
FLACS is a comprehensive, yet easy to use, software tool for modelling (dispersion, fire and explosion) consequences in full 3D for all typical flammable and toxic release scenarios. It is used extensively in the Oil and Gas and Process industries and also increasingly in the nuclear industry, in facilities with dust explosion potential and many other fields. By modelling with CFD (Computational Fluid Dynamics) in full 3D it is possible to predict consequences much more accurately and to include the effect of all contributing and mitigating effects (such as confinement and congestion due to real geometry, ventilation, deluge). A better understanding and higher accuracy of results not only contributes to raising the true level of safety but also allows designers to choose truly effective design options and mitigation measures and thereby improving both safety and cost effectiveness.
