AI Technical Summary

Technical Problem

Existing technologies struggle to accurately characterize the enhanced sediment transport mechanism under oscillating flow when dealing with scour protection of offshore wind turbine foundations, resulting in insufficient protection reliability. In particular, in environments with strong unsteady wave oscillating flow, the phase response prediction of velocity and pressure gradient within porous media is distorted, and it is difficult to identify the topological structure of horseshoe vortices and wake vortices, affecting the accuracy and efficiency of the design.

Method used

A multi-physics parallel computing approach was adopted to construct a coupled model of the flow field, wave field, and sediment transport field. An adaptive coupling strategy based on unsteady seepage calculation of inertial terms and identification of vortex structures was used to correct the sediment initiation conditions. The flow field velocity, wave pressure, and sediment scour depth were calculated in parallel through a spatial adaptive coupling strategy to optimize the design parameters of the protection project.

Benefits of technology

It has achieved high-precision and high-efficiency optimized design of protection engineering under complex sea conditions, improved the accuracy of protection effect and calculation efficiency, and ensured the stability of offshore wind turbine foundations.
