AbstractThis paper presents work on the investigation of air entrainment in balcony spill plumes in the under the balcony and the rotating regions using CFD modeling and full-scale experiments. Mass flow rates near the balcony area were examined to evaluate the applicability of existing balcony spill plume correlations. The results of this study were used to develop an empirical correlation to calculate air entrainment rate at the spill edge. This correlation considers the various factors affecting air entrainment under the balcony area and the rotating region. Comparisons between model predictions and experimental data indicates that the CFD predictions agree well with experimental data both of which show a large degree of air entrainment into the rotating flow.
