| Abstract |
In a wind tunnel study, the influence of the highly turbulent region found in the lee of a model building upon plumes emitted from short stacks was examined through smoke visualization and tracer gas concentration mappings. The study was conducted in the Meteorological Wind Tunnel of the EPA Fluid Modeling Facility. A thick, simulated atmospheric boundary layer was used to provide background dispersion. A rectangular shaped building with its length equal to twice its height and width was oriented perpendicular to the approaching wind. In all phases of this study each situation was repeated with the building removed. This allowed for a simple demonstration of the building wake effects. A simple mathematical model provided good estimates of concentrations in the building wake. The building influence was found to be reduced with increases in the effective source height. Application of the '2 1/2 times rule,' that is, an effective source height greater than 2 1/2 times the height of the building, avoids significant influence by the building on the maximum ground-level concentration. |
