PROGRESS IN PHYSICAL MODELING FOR WIND ENGINEERING

Physical modeling has and continues to be the primary source of information for wind-engineering applications. The capability of boundary-layer wind tunnels to simulate essential features of the atmospheric boundary layer makes this possible. Recent efforts to simulate special aspects of natural winds by modifications to conventional boundary-layer wind tunnels and new types of flow facilities are described. Several instrumentation developments are presented that extend the capability to measure fluctuations of various quantities for studies of air pollutant concentrations and wind loads and pressures on buildings and other structures.
