HO-2696 (RP-204) -- The Effect of Varying Exhaust Stack Height on Contaminant Concentration at Roof Level ✓ Most Recent

This paper will deal with the second part of a two-part study by Wilson that was completed in 1979 to develop simple quantitative stack design procedures. The first part of the study used flow visualization to determine the necessary stack height required to avoid all contact between the exhaust gas plume and roof level air intakes. The second part of the study in which concentration measurements on building models in a wind tunnel were used to predict the effect of varying stack height.
