I am looking for a reference (book or peer-reviewed article) which computes turbulence flow across a flat plate with DNS in 2d. All I found were 3d cases (e.g. Spalart 1988) or 2d with a turbulence model (e.g US wind verification). I am specially interested in a grid, that is fine enough and is proven to be so.

Would it be ok to take a 2d slice from one of the 3d models? I am aware of the fact, that turbulence is a three-dimensional effect. But 3d is too difficult in my case.

You cannot find a 2D DNS on flat plate simply because it does not exist, it is 3D and it is necessary to have the three-dimensionaly preserved to allow turbulence to develop from initial homogeneous velocity..

Ok, thanks for the confirmation.

What is the smallest grid to have turbulence over a flat plat in 3d? I want to use a classical MAC scheme. Most references use millions of grid points, I'd like as few as possible

you need O(10^9) nodes
