Description:
The paper discusses the development of a two-dimensional turbulentkinetic energy - dissipation rate (k-epsilon) turbulence model inthe form of vorticity and stream functions. his turbulence modelprovides the distribution of turbulent kinematic viscosity, used tocalculate the effective turbulent diffusion coefficient. hesevalues were incorporated into the particle diffusion equation fordetermining the contaminant concentration profiles within anoccupied space. he effects of locations of the supply air ductand the contaminant source on particle concentration distributionand ventilation effectiveness were investigated.
