摘　　要：该文采用基于开源代码计算流体力学工具包Open FOAM开发的船舶与海洋工程水动力学求解器naoeFOAM-SJTU,对一座Spar模型的硬舱部分进行了涡激运动的数值模拟。采用大涡模拟方法数值模拟了不同折合速度下Spar模型的涡激运动情况,并与Finnigan等[1,2]的模型试验结果作了对比和分析,证明了求解器naoe-FOAM-SJTU在模拟涡激运动方面的可靠性。This paper applies a naoe-FOAM-SJTU solver for solution of ship and ocean engineering flows based on the open source CFD toolkit Open FOAM to simulate the vortex-induced motions of the hard tank section of a Spar model. The spar VIM was simulated by using large-eddy simulation in naoe-FOAM-SJTU solver at different reduced velocities. The numerical results are compared with the results of model tests which were performed by Finnigan, et al（2007）[1,2] to evaluate the reliability of the naoe-FOAM-SJTU solver in VIM simulations.
