Use of CFD for better understanding of dispersion over complex terrain

Accidental release and dispersion of toxic and flammable gases were always major hazards for public health and safety that process industries had to deal with. Real terrain dispersion simulation for risk analysis purposes poses specific difficulties related to complex turbulence phenomena development, especially when obstructions are present in flow region. With the ever growing computational power and better understanding of theory underlining physical phenomena, computers are going to play vital role in gaining better and in-depth understanding of real terrain dispersion
