CFD represents the state-of-the-art in consequence effects modelling for ventilation, flammable and toxic gas dispersion, smoke and explosion. Several design aspects can benefit from the use of CFD models as an alternative to the simplified consequence models; these include the dispersion of dense gases in low wind conditions, the assessment of explosion risk in congested areas, the dispersion of gases in complex terrains and hot plume dispersion from a ground flare.
Use of CFD provides realistic results which can provide considerable benefits in the design of the facilities especially for facilities where space is a constraint.
