Abstract

In this study, characteristics of spatial correlation of fluctuating wind velocity around rectangular cylinder with the side-ratio 1, 3 were experimentally investigated by wind tunnel testing. For slender rectangular cylinder, Strouhal components are dominant and have a phase difference on longitudinal axis. According to consideration of frequency analysis, longitudinal correlation length was derived from a Gaussian function model fitting to coherence. To obtain windward correlation length, auto-correlation function of the wind speed time series and ERA method were employed. Correlation length derived from the method was discussed.
