Wind tunnel measurement dataset of turbulent flow around two-dimensional ridges and three-dimensional hills with smooth and rough surfaces
Description
This is a dataset of turbulent flows over two-dimensional (2D) ridges and three-dimensional (3D) hills with smooth and rough surfaces measured in a boundary layer wind tunnel. The dataset is based on the study reported in the research article entitled “A wind tunnel study of turbulent flow over a three-dimensional steep hill” by Ishihara, Hibi and Oikawa (1999), which examined the mean flow and turbulence characteristics over a 3D steep hill and its near-wake dynamics. The three velocity components on multiple representative horizontal and vertical planes around the hilly terrains were measured under different surface roughness conditions. Mean and fluctuating velocity profiles in the wake region are presented along with details of the measurement and data acquisition procedures.
