Abstract
In wind tunnel experiment, PIV (Particle image velocimetry) technology has improved and been able to catch the high frequency turbulent fluctuations. We can acquire time-dependent three-dimensional wind velocity components directly by stereo PIV. We suggest that stereo PIV measurement data of turbulent boundary layer are imposed to inflow condition of the computational domain of LES. This paper presents the result of stereo PIV measurement results for turbulent boundary layer on flat floor, and we discuss the accuracy of stereo PIV measurement to apply to inflow condition of LES.
