Determination of Height for Stack near Building--Wind Tunnel Study
Wind tunnel tests were conducted to determine the validity of the 'two-and-one-half-times' rule frequently used to calculate a necessary height for a stack in the vicinity of a building. Model stacks and buildings were placed in a simulated atmospheric boundary layer in a meteorological wind tunnel. Smoke was used for flow visualization and methane for quantitative concentration measurements downwind of the building. These studies showed that the two-and-one-half-times rule for the determination of a necessary stack height in the vicinity of a building is adequate for a building whose width perpendicular to the wind direction is twice its height, but that it is unnecessarily conservative for a tall thin building. An alternative rule, called Briggs' alternative, was shown to be adequate.
