Abstract
A computational fluid dynamics code has been used to model buoyancy-driven displacement ventilation flows. The results of using two eddy viscosity turbulence models are compared with those of mathematical theory and salt bath experiments carried out at the University of Cambridge. The work highlights some of the difficulties involved in modelling buoyancy-driven flows and identifies a preferable turbulence model for predicting such flows.Keywords
