Experimental datasets of green water phenomenon on rectangular structure
Abstract
The experimental dataset is presented for flow kinematics and pressure distribution of green water phenomenon on a rectangular structure. The green water experiments were performed in a 2-D wave flume with a fixed structure varying its flare angle under regular wave conditions. The structure and wave conditions were determined by scaling down with a ratio of 1:125 from the BW Pioneer Floating Production Storage and Offloading (FPSO) operated in the Gulf of Mexico. The experimental dataset includes the wave elevation, water velocities measured using Particle Image Velocimetry (PIV), bubbly flow velocities measured using Bubble Image Velocimetry (BIV), and pressure distributions obtained on the surface of the structure using the pressure sensors. The presented dataset can improve understanding of the physical kinematics of green water loading, which has a violent multi-phase flow and high-nonlinear characteristics. The dataset also can be used as benchmark data for numerical models to estimate the green water loading on ships and offshore structures.
