Our “Grand” challenges


Rough “wall” boundary layers
-

difference between atmospheric boundary
-
layer and flat
plate boundary layer.

Why is the turbulent flow structure different?


Why don’t we see transition to turbulence as a classical mechanism in linear/nonlinear
stability theory?


Why do the eigenmodes of a laminar flow often provide a good description of turbulent
structures?


Turbulence versus coherent mixing (high Reynolds number versus low Reynolds
number).
Both unsteady processes


Computation


Lack of resources in Australia!


Sub
-
grid closure models still important.
