WIND-TUNNEL INVESTIGATIONS OF INTERFERENCE EFFECTS ON PRESSURE DISTRIBUTION ON A BUILDING

This paper presents wind tunnel investigations of the aerodynamic interference effects on the pressure distribution on a building adjacent to another one. Tests were carried out at the Aviation Institute in Warsaw. Models, made to 1 : 100 scale, were set up behind a turbulent flow development system. It has been found that for some wind directions local values of the external pressure coefficient on the leeward wall, close to the gap between buildings, may be 2.5 times higher than on an isolated building, This may also lead to a reverse draught in the natural ventilation system of the apartment buildings.
