CFD simulations of transient fuel gases mixing, leakage and flammability in air

Dispersion of fuel gases in air is very rapid during accidental release which can lead to minor asphyxiate to major explosion. Leakage of fuel gases poses an unseen threat due to odourless and colourless properties of gas components. A complete understanding of fuel gases mixing behaviours with air...
