|
- Stratification
accurately suppresses the vertical component
|
|
(measured as less
than 3 percents of the horizontal component)
|
|
|
- The velocity
profile across the layer is parabolic at all times and
|
|
|
quickly returns
to this state if perturbed (the time constant has been
|
|
measured to be on the order
of 0.2s)
|
|
|
- Under these
circumstances, the equations governing the flow are
|
|
|
2D Navier Stokes
equations + a linear friction term
|
|
|
- Systematic
comparison with 2D DNS brings evidence the system
|
|
|
behaves as a
two-dimensional system
