| 摘 要： | 为在初步设计时预测ROV的水动力性能,使用CFD技术进行分析,以ROV模型为例,最大程度地保留ROV内部的构件,使模型更加接近真实状况。分别计算ROV在不同工况下的阻力、不同漂角下的横向力和转艏力矩以及添加体积力模型之后的螺旋桨流场状况,很好地模拟出ROV周围的流场,并与已有的试验数据进行对比。结果验证了CFD水动力仿真的可行性和准确性,并还可预测ROV在螺旋桨作用下的进速等,对ROV设计具有实际的参考价值和指导意义。

| Abstract: | The hydrodynamic performance of ROV is very important for its safety and stability, CFD technology is used to predict the hydrodynamic performance of ROV in the preliminary design. For example, the internal component of ROV was held to the most extent, making the model more close to the real one. Resistance under different working conditions , lateral forces and turning moment at different drift angles and flow condition with propeller body force was calculated in this paper, which simulated the flow filed very well. Comparing with the previous experimental data, they verified the feasibility and accuracy of CFD hydrodynamic simulation. Furthermore, the speed of ROV with propeller can be predicted, which has practical reference value and guiding significance. |
