Abstract: L15.00006 : Validation of CFD Predictions of Wave Propagation and Forces on a Cylinder in a Long Flume*
9:05 AM–9:18 AM
The objective of this initial study is to validate CFD predictions of the pressure distributions on a cylinder resulting from wave-only loading conditions. Numerical results from multiphase 2D and 3D RANS simulations using the OpenFOAM toolbox will be validated against experimental data of regular surface waves propagating down the OSU Large Wave Flume in still air and interacting with a steel cylinder. The full 87.64m flume is included in the CFD domain. Surface elevations, velocity profiles, wave run-up on pile, and pressure distributions will be compared. The sensitivity of the numerical wave and wind profiles to various model parameters is investigated.
Preliminary results show good agreement between numerical and experimental results. The findings of this study will be used to inform next steps toward validated simulation of coupled wind-wave loading on coastal structures.
