 The data was obtained from direct numerical simulations of open and closed channel flow using a pseudo-spectral method which solves the wall-normal velocity/vorticity formulation of the Navier-Stokes equation introduced by Kim et al (1987). The flow domain contains Nx*Ny*Nz grid points with equidistant grid spacing in x and z direction and a Chebyshev-Gauss-Lobatto (CGL) grid in y direction. Note that the open channel flow simulations feature a grid refinement towards both the no-slip and the free-slip boundary condition.
