ABSTRAKT

A direct numerical simulation (DNS) of turbulent channel flow has been carried out to understand the effects of Reynolds number. In this study, the Reynolds number for channel flow based on a friction velocity and channel half width was set to be constant; Reτ = 1100. The number of computational grids used in this study was 1024 × 1024 × 768 in the x-, y- and z -directions, respectively. The turbulent quantities such as the mean flow, turbulent stresses and the turbulent statistics were obtained via present DNS.
