为了研究波流对水平圆柱的影响，本文对水平圆柱体上的波流力进行研究。首先对数值模型进行验证分析，其次对不同工况下的波流力与自由液面变化进行数值模拟。研究结果表明，对于部分淹没的水平圆柱，波浪的反射与阻塞作用随着波幅的增加而增加，波流力随着波幅与垂向位置的增大而增大，正垂向力随着频率的增大趋于某一特定的值。对于淹没的水平圆柱，随着垂向位置的增加，波反射减小，波阻塞变大且大于波反射。
In order to study the influence of wave -current on a horizontal cylinder, the wave-current force on the horizontal cylinder is studied in this paper. Firstly, the numerical model is verified and analyzed, and then the wave-current forces and the free surface deformation under different conditions are simulated.The results show that: For partially submerged horizontal cylinder, the wave reflection and blocking effects increase with the increase of wave amplitude, the wave-current forces increase with the increase of wave amplitude and vertical position, and the positive vertical force tends to a certain value with the increase of frequency. For the submerged horizontal cylinder, with the increase of depth, the wave reflection decreases and the wave reflection increases and is greater than the wave reflection.
