海上风机结构周围冲刷数学模型研究

摘要

Based on the open source software,OpenFOAM,and dynamic mesh method,a mathematical model for the local scour of offshore wind turbine foundation is developed using the principle of equilibrium of bed shear stress. The model is applied to simulate the flow and local scour around circular pile foundations. The simulated results of flow and scour depth agree well with the experimental data.%基于开源程序OpenFOAM和动网格技术，利用切应力平衡法建立水流作用下的海上风电基础局部冲刷数学模型。通过模拟结果与实验数据的对比发现，所建立的冲刷数学模型能够合理反映圆柱型单桩基础周围的水流结构，冲刷深度与实验结果吻合较好。
