Criterion for wind environment assessment with consideration to the effect of turbulence
Turbulence affects the human perception of wind, the wind-induced damage to buildings, the values of wind speeds measured by 3-cup anemometers, and so on. The wind environment assessment criterion proposed by the Wind Engineering Institute Co., Ltd. is based on the relationship between the mean wind speeds measured by 3-cup anemometers and the condition of surrounding terrain. This criterion does not consider the influence of turbulence. Considering the significant urbanization of large cities and the change in anemometers used for wind speed measurements, a new criterion of wind environment assessment that considers the effect of turbulence is required. The present study discusses such a criterion based on a wind tunnel experiment, the observation at various locations, and a questionnaire survey on the wind environment that was conducted with for the residents and pedestrians in Tokyo.
Kryterium oceny środowiska wiatrowego z uwzględnieniem wpływu turbulencji
Streszczenie
Turbulencja wpływa na postrzeganie wiatru przez człowieka, wywołane wiatrem uszkodzenia budynków, wartości prędkości wiatru mierzone przez anemometry 3-filiżankowe etc. Kryterium oceny środowiska wiatrowego zaproponowane przez Instytut Inżynierii Wiatrowej opiera się na zależności między średnią prędkością wiatru mierzoną przez anemometry 3-filiżankowe a stanem otaczającego deszczu. To kryterium nie uwzględnia wpływu turbulencji. Biorąc pod uwagę znaczną urbanizację dużych miast i zmianę anemometrów używanych do pomiarów prędkości wiatru, wymagane jest nowe kryterium oceny środowiska wiatrowego, które uwzględnia wpływ turbulencji. Niniejszy artykuł omawia takie kryterium oparte na eksperymencie z tunelem aerodynamicznym, obserwacji w różnych miejscach oraz ankiecie dotyczącej środowiska wiatrowego, która została przeprowadzona dla mieszkańców i pieszych w Tokio.
