Improvement of outdoor ventilated environment contributes not only to energy-saving and suppression of CO2 but also to indoor air quality and its comfort. To consider outdoor well-ventilated environment, a flow field within ideal urban canyons has been investigated by wind tunnel experiment, but the behaviors of turbulence and mean characteristics of canyon vortices within real urban canyons are still not comprehended. In this study, a wind tunnel experiment for a real apartment complex was conducted to confirm the reproducibility of flow field within the canyon. The apartment complex is located at Musashino city, Tokyo, where field measurement was conducted. The buildings with a height more than two-stories were resolved within 200m radius under the model length ratio of 1/150 was measured using both PIV (Particle Image Velocimetry) and LDV (Laser Doppler Velocimeter). These measurements at 5 points within the urban canyon were compared with field measurement values. The wind velocities and turbulent intensities obtained by both PIV and LDV fairly agreed with the field measurement values within the urban canyons, though a small-scale surface roughness like a balcony was not modeled in the present wind tunnel experiment.
