| dc.description.abstract | The flow field around surface-mounted obstacles were experimentally investigated in this study. The experiments were conducted in large-scale wind tunnel. The turbulent velocity, kinetic energy, dissipation rate and vorticity distribution were measured by a split-film thermal anemometer and an automatic transversing system. The influence of the aspect ratio of obstacle was systematically studied in this research. The experimental results reveal that the separated shear layer on the top of the obstacle grows stronger as the width and height ratio increases. Also, the wake flow of the obstacle does not have periodic vortex shedding like that of cylindrical wake. | en_US |
