| 概要 |
Wavelet analysis is tested using the data from a simulation of turbulent atmospheric boundary performed in a wind channel. Model of urban streets is positioned on the test section floor. The large siz...e of the model has led to high value of the roughness. Experiment involves hot-wire (HWA) and time-resolved Particle Image Velocimetry (TR-PIV) measurements inside the street canyon. Wavelet analysis applied to the velocity data results in information about frequency spectrum and temporal location of energetic harmonic structures in the flow field. Comparison of the HWA results with those obtained by PIV has shown agreement of spectral characteristics, confirming the legacy of their application. Total power spectra from different position in the street canyon were analysed and mutually confronted.続きを見る
