摘　　要：本文采用粘流数值模拟方法,通过Workbench搭建双向流固耦合求解器,对粘液析出的柔性平板减阻效果进行数值模拟研究。结果表明,耦合粘液析出与柔性覆盖层可进一步提升减阻效果。粘液与柔性平板耦合之后,起到了进一步减阻的作用。从减阻效果来说,粘液与柔性平板的减阻技术可行,能在粘液减阻基础上进一步减少16.3%~21.20%。The viscous numerical simulation is employed to investigate the drag reduction characteristic of flexible plate coupled with the mucus by using of the commercial software Ansys workbench.The simulation results show that the coupled method of flexible plate and mucus can do further good on drag reduction.In specific,at least 16.3%~21.2%drag reduction ratio can be achieved by using the coupled drag reduction method.
