Abstract The paper discusses the development of a two-dimensional turbulent kinetic energy-dissipation rate (k-epsilon) turbulence model in the form of vorticity and stream functions. This turbulence model provides the distribution of turbulent kinematic viscosity, used to calculate the effective turbulent diffusion coefficient. These values were incorporated into the particle diffusion equation for determining the contaminant concentration profiles within an occupied space. The effects of locations of the supply air duct and the contaminant source on particle concentration distribution and ventilation effectiveness were investigated.
