Turbulent Boundary Layer (DNS)

New high-quality movie of a turbulent boundary layer studied by direct numerical simulation (DNS) 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. See also a similar video with extended introduction:    • Turbulent Boundary Layer (APS Gallery...  , and a corresponding LES movie:    • Turbulent Boundary Layer (LES)  .

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 8192x513x768 spectral modes.
