Abstract
Three different DNSs of plane turbulent Couette flow at Reynolds number 1300 were carried out with varying computational boxes and numerical resolution. Different box sizes in combination with periodic boundary conditions were observed to yield different realizations of the flow field. The differences were mainly associated with the largest scales of motion which had significant impact on the one- and two-point correlations of the streamwise velocity. The ability of finite-difference DNSs to reproduce higher-order turbulence statistics in the near-wall region has also been discussed.
