| 摘 要： | 采用以颗粒动力学为基础的Euler-Euler双流体模型和计算流体动力学(CFD)技术模拟涡激振动下的管道内部液固两相流流动,研究了涡激振动对深海采矿矿物颗粒水利提升的影响.通过对3种涡激振动工况下液固两相流流场计算分析,发现管道的涡激振动会改变颗粒轴向速度分布和颗粒浓度分布.在涡激振动作用下颗粒轴向速度分布发生"波动"现象,颗粒浓度分布发生周期性的变化,局部浓度明显提高. |

| Abstract: | In order to study the influence of vortex induced vibration(VIV) on mineral particles hydraulic transportation in the deep sea mining, Euler Euler two fluid flow model based on particle dynamics and CFD are employed to simulate the liquid solid two phase flow field in pipe under VIV. Through the analysis of liquid solid two phase flow field under several VIV conditions, it is found that VIV changes the axial velocity and concentration distribution of particle. The fluctuation phenomenon of the particle axial velocity occurs, the particle concentration distribution varies cyclical and local concentration increase significantly. |
| Keywords: | deep sea mining mineral hydraulic transportation vortex induced vibration liquid solid two phase flow |
