利用物理模型实验,测量了海底管线在波良作用下的水平力和升力,并应用Morison方程及流函数理论,按最小二乘原理得出C_D和C_M以及C_L,讨论了它们与Kc,Re及间隙比e/D的关系.本文还应用边界拟合坐标及二维流场的大涡模拟法,模拟了与实验相同工况下海底管线的受力及流场情况,并把物理模型实验和数值模拟的结果进行了比较. The physical model experiment was used to measure the horizontal force and lift of submarine pipeline under the influence of the wave, and Morris equation and flow function theory were used to obtain C_D, C_M and C_L according to the principle of least squares, and their relationship with Kc, Re and Gap ratio e / D. In this paper, large-eddy simulation of boundary-fitted coordinates and two-dimensional flow field is also used to simulate the force and flow field of submarine pipeline under the same working conditions. The physical model experiment and The numerical simulation results are compared.
