Turbulent Boundary Layer (APS Gallery Submission)

High-quality movie of a turbulent boundary layer direct numerical simulation (DNS) and large-eddy simulation (LES) performed in 2010, reaching up to Re_theta=4300. Simulations were performed with up to 7.5 billion grid points on the Ekman cluster at KTH Stockholm. More information and simulation data: http://www.mech.kth.se/~pschlatt/DATA. Movie with better resolution: http://arxiv.org/abs/1010.4000

Results of this DNS are described in Schlatter and Orlu, 2010, Journal of Fluid Mechanics, 659, 116-126.

The simulations use a spectral discretisation of the incompressible Navier-Stokes equations on a grid with up to 8192x513x768 spectral modes.

Simulation code: Simson (http://www.mech.kth.se/~mattias/simson-user-guide-v4.0.pdf)

I know what the boundary layer is and how to remove it
