Building wake effect
WebDec 1, 2004 · Stack and building downwash cause an increase of ground-level concentrations, because of two concomitant phenomena: (i) the drag of the effluent in the stack and/or building wake—since this wake extends below the stack outlet, this drag causes the plume to decrease in height; (ii) the increase of entrainment with ambient air … WebThe experiments on Governors Island were necessary to examine the effects of natural ventilation (door control) and positive pressure ventilation on a fire. The experiments would also allow researchers to study the means of egress in the building, and how conditions were affected by the use of wind control devices and high-rise nozzles. These
