PROGRESS IN PHYSICAL MODELING FOR WIND ENGINEERING

Physical modeling has and continues to be the primary source of inform ation for wind-engineering applications. The capability of boundary-la yer wind tunnels to simulate essential features of the atmospheric bou ndary layer makes this possible. Recent efforts to simulate special as pects 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 pollu tant concentrations and wind loads and pressures on buildings and othe r structures.
