- Abstract
- The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) initiated a project to evaluate the balcony spill plume equation used in North American codes and standards (RP-1247). AHRAE engaged the National Research Council of Canada (NRC) to use computational fluid dynamics (CFD) modeling and full-scale experiments to investigate smoke flow in balcony spill plumes and the resulting mechanical exhaust requirements for an atrium. Part 2 of the research paper reports results of the measurements in the simulated atrium area. It includes an analysis of the data to estimate the mass flow rate at the end of the balcony and the air entrainment in the atrium space. The experimental entrainment rates are compared with algebraic equations, which are used to estimate the mass flow in an atrium.
