CH-99-07-2 (RP-805) -- Influence of Architectural Screens on Rooftop Concentrations Due to Effluent from Short Stacks PDF

This paper describes the wind tunnel study conducted on behalf of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to evaluate and quantify the effect of architectural screens on rooftop concentration levels due to effluent from short stacks. An equivalent stack height (ESH) concept is introduced, which is used to develop a stack height reduction (SHR) factor that may be used in conjunction with existing stack design procedures found in the 1997 ASHRAE Handbook - Fundamentals to account for the presence of architectural screens.
