【摘要】：海上风机基础长期受到海流、波浪等环境荷载的交互作用,作业难度较大,研究风机基础的水动力特性可为其设计及应用提供重要参考.文中基于自主研发的船舶与海洋工程CFD求解器naoe-FOAM-SJTU,对一座固定式高桩承台风机基础在波流作用下的水动力参数进行数值模拟,研究了波浪与海流联合作用时,该风机基础在不同水深、不同波高条件下的受力、表面压力以及波面爬升现象,并与上海交通大学海洋工程国家重点实验室的模型试验结果进行比较,计算结果显示naoe-FOAM-SJTU求解器可以很好地模拟波流联合作用下风机基础的水动力特性.
[Abstract]:The foundation of offshore fan is subjected to the interaction of current, wave and other environmental loads for a long time, so it is difficult to operate. The study of hydrodynamic characteristics of fan foundation can provide important reference for its design and application. Based on the independently developed CFD solver of ship and ocean engineering, naoe-FOAM-SJTU, the water of a fixed pile cap fan foundation under the action of wave and current is studied in this paper. The dynamic parameters are numerically simulated, In this paper, the forces on the foundation of the fan under different water depth and wave height, the surface pressure and the wave surface climbing are studied when the combined action of wave and current is carried out. Compared with the model test results of the State key Laboratory of Marine Engineering of Shanghai Jiaotong University, the calculation results show that the naoe-FOAM-SJTU solver can well simulate the hydrodynamic characteristics of the fan foundation under the combined action of wave and current.
