Computational fluid dynamics study on two-phase CO2 dispersion in a neutral atmosphere
conference paper
Abstract: A large release of Carbon Dioxide (CO2) is modelled with Computational Fluid Dynamics (CFD), (Fluent v12.1). Special attention is given to the modelling of a neutral atmospheric boundary layer (ABL) with gravity. Both the presence of non-vapour CO2 and the high density of CO2 require that the effect of gravity is taken into account. The ABL describes the velocity and turbulence properties as a function of height, these strongly influence the mixing and dispersion of the hazardous substance with the surrounding air. Profiles for the ABL are obtained which are constant over the length of the calculation domain. The CO2 release is modelled as both a gas release as a twophase release.
