The study described consisted of wind-tunnel experiments to determine the flowfield created within a box-like structure containing two windows. Three configurations of the structure were investigated. The pressure distributions on the closed windows and the pressure at the same locations with open windows were measured and related to the approach flow. The mean air speed and the turbulence intensities near the windows and at various locations inside the rooms were measured using an omni-directional hot-film probe and a vertical, cylindrical hot-film probe. The air speed inside the room and at the windows was related to the approach flow and the pressures on the closed windows. Flow visualization using smoke and cotton tufts was used to study the flow patterns and the direction of the air flow at various locations inside each structure. Black and white photographs showing the basic features of the flow are presented.
