Description:

The research objective of this Faculty Early Career Development (CAREER) program project is to define the tropical cyclone surface wind field, wind-driven rain characteristics and wind loading in the built environment. The goal is to determine how localized, coherent features occurring in the rough-wall turbulent boundary layer and larger-scale convective features (such as meso-vortices, rainband core downdrafts) influence the surface wind field characteristics and loading on low-rise structures.

Description:

This dataset comprises an extensive series of experiments conducted in a large boundary layer wind tunnel (BLWT) to investigate the effects of upwind terrain on surface pressures acting on a low-rise building. Three geometrically scaled models of the Wind Engineering Research Field Laboratory (WERFL) building were immersed in 33 boundary layer flows through precise adjustment of an automated roughness element grid called the Terraformer. The roughness configuration of the Terraformer was modulated to simulate a variety of upwind terrains ranging from marine to dense suburban. Simultaneous pressure measurements were collected on the surfaces of three models of the WERFL building with geometric scales of 1:20, 1:30, and 1:50. For each model, surface pressures were obtained for three wind directions (0, 45, and 90 degrees), 16 roughness element heights, and two element orientations (wide and narrow edge windward).
