Dataset Description

The dataset within this project aims to provide the scientific community and all port stakeholders with an experimental benchmark consisting of a characterization of the wind field and aerodynamic coefficients on containerships and port infrastructures under extreme winds. Experiments were performed on containerships and port infrastructures within the WindEEE Dome including ABL, downburst-like, downburst-like embedded in ABL, and tornado-like winds. Each wind system was first tested in the empty test chamber in absence of models. Following the empty test chamber measurements, the ship was tested for five different container arrangements within each flow.

S1. Wind Profile Development (PRF)

Simultaneous surface wind velocity measurements were taken to characterize wind profile of atmospheric boundary layer (ABL) flows, downburst-like flows, and combined ABL–downburst flows. Three-component wind velocities were measured using Turbulent Flow Instruments (TFI) Cobra Probes which were mounted on to a vertical rack at heights of 2.5, 5.0, 7.5, 10.0, 20.0, 30.0, and 50.0 cm above the ground surface. The following experiments were performed with the rack positioned at its primary position. The rack was then moved forward, rearward, left, and right by 40.0 cm and each experiment was repeated. This configuration resulted in profiling measurements at 5 locations.

E1. Atmospheric Boundary Layer (ABL) Flow Profile

An atmospheric boundary layer (ABL) flow representative of over sea-like surface and open-country type terrain was generated using the 60-fan wall located on one side of the hexagonal WindEEE test chamber. To establish the ABL profile, 13 triangular spires were installed upstream of the measurement location for the open-country type terrain flow. Each spire measured 120 cm in height and 20 cm at the base, and the array was positioned 100 cm downwind from the 60-fan wall. The spires were designed to induce a vertical wind-speed gradient and turbulence intensity profile consistent with an open-country ABL, promoting flow development prior to the model testing position. ABL wind of various strength were generated by operating the fans at the 60%, and 90% of their rated fan speed. These experiments are indicated by the profile config value ‘CC-2091’, ‘CC-2051’, ‘CC-2090’, and ‘CC-2005’, within the test file name.

E2. Downburst-like (DB) Flow Profile

In the WindEEE Dome, an impinging-jet style downburst was created by releasing pressure from a plenum above the test chamber. The resulting flow began as a high-velocity jet striking the ground, which then spread outward in a radial outflow. To control the flow, the upper fans were operated at 30% of their capacity, and the downburst bellmouth, with a diameter of 3.2&n
