Numerical simulation and experimental study on flow around submarine pipeline with spoiler

In order to study the characteristics of flow around the submarine pipeline with spoiler,a novel method using experiment and numerical simulation is proposed in this paper.The numerical model is discredited by finite volume method and selects standard k e turbulence model.By contrastive analysis,the numerical results agree well with the experimental results.In addition,the spoiler's influences on the stagnation point of upstream,velocity field,pressure distribution of pipeline,drag coefficient,lift coefficient,and the seabed shear stress at various gap ratios are investigated.These results might be useful for further study of submarine pipeline erosion and protection.
