Numerical simulation of pollutant dispersion in a test ventilated room

The paper presents the numerical study of 3D flow and neutrally buoyant pollutant transport in a model atrium under conditions of test experiment by Thatcher et al. (2004) with a controlled uranine dye spill. For the Reynolds number of 2160 the Reynolds-Averaged Navier-Stokes approach was applied. A...

Summary:The paper presents the numerical study of 3D flow and neutrally buoyant pollutant transport in a model atrium under conditions of test experiment by Thatcher et al. (2004) with a controlled uranine dye spill. For the Reynolds number of 2160 the Reynolds-Averaged Navier-Stokes approach was applied. Analysis of CFD predictability for a steady-state fully-developed regime and a transient process was done in comparison with the experimental data on contaminant concentration fields. For various positions of the contaminant source the ventilation effectiveness was computed and discussed.
