Application of CFD (Fluent) to LNG spills into geometrically complex environments

Numerical investigation of VOC levels in the area of petrol stations

“…Albriet et al (2010), Uhrner et al (2007), Wang and Zhang (2012), and has also been applied by various researchers to investigate hydrogen diffusion related to hydrogen refueling, Kikukawa (2008), Papanikolaou and Venetsanos (2007), the leak of hydrogen and methane from high pressure pipelines, Wilkening and Baraldi (2007), as well as the diffusion of LNG vapours, Gavelli et al (2008) or dense gas releases in buildings (Gilham et al, 2000). However, there is a lack of numerical simulations of the spatial concentration of VOCs originating typically from gasoline in the areas of petrol stations.…”

Hazardous gas dispersion: A CFD model accounting for atmospheric stability classes

“…Falcon test 1 has been selected since it involves a stable stratification where atmospheric turbulence reduction is more important and consequently the atmospheric turbulence model ASsM proposed in this work plays a major role. Moreover, literature data obtained using the Reynolds Stress Model (RSM) for this test are available as a reference [25].…”

An integrated emergency response model for toxic gas release accidents based on cellular automata

“…Though such models provide quick prediction of toxic gas concentration, their critical assumptions are hard to meet in real accidents, which may reduce the accuracy and reliability of their prediction outcomes (Gailis and Hill 2006;Sanchez et al 2013;Sklavounos and Rigas 2012). Recently, the dispersion process of toxic gas usually has been simulated by computational fluid dynamics (CFD) models, especially when the external environment conditions are complex (Gavelli et al 2008;Hanna et al 2009;Zhang et al 2014). However, CFD models require massive amounts of input data and long computation time (Antonioni et al 2012).…”
