Wind tunnel measurement dataset of turbulent flow over two-dimensional ridges and three-dimensional hills with smooth and rough surfaces.

ABSTRACT: This paper presents a high-spatiotemporal-resolution 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. This dataset extends the experimental measurements reported in the research article entitled "A wind tunnel study of turbulent flow over a three-dimensional steep hill" by Ishihara et al. (1999). In addition to the original 3D smooth surface case, new measurements on 2D smooth and rough ridges and a 3D rough hill are conducted to clarify the effects of surface roughness and topography on the hill-induced flow field. The three velocity components on multiple representative horizontal and vertical planes around the hilly terrains were measured under different surface roughness
