有搞的盖驱动流的吗？即：封闭空抢种的流体由于底盖的剪切力作用而流动。这种问题一般采用什么模型呀？

I am not familar with this work. But what do you mean "采用什么模型呀"? turbulent models?

谢谢！
能采用高雷诺数的k-e模型吗？属于湍流吗？
能不能因为具有回流将其归为湍流？又根据什么将它归为高雷诺数或低的？

same as to your previous problem.
In general, turbulent models are mostly referring to high reynolds number, as to what I know. Low reynolds number models are applied to wall region.
In other words, turbulence models up to now are mainly confined to fully developed turbulence. The transition region is difficult to model, NASA have researcher doing this field but no many publications.

Is it necessary to introduce two more equations(k-e)? If it is not necessary, it will waste time and energy in the programming for k & e.

Do you have experimental data about this case?
If so, first you calculate by using laminar flow assumption and compare. If not good, using k-e, which is the simplest turbulent models.
