Abstract

This paper investigates the characteristics of turbulent flow in the wake of two different building models. Particle image velocimetry is applied to measure the instantaneous velocity fields around the buildings. Proper orthogonal decomposition method is employed to analyze the complex turbulent flow field and the peak velocity excursions of each mode are extracted to reveal the dominant fluctuation patterns of the building wakes. The results suggest that these extreme patterns follow similar rules in influencing the instantaneous wind velocity fields while they are used to reconstruct the experimental data.
