In this chapter, a high order direct numerical simulation (DNS) is applied to
generate fully developed turbulent inflow. The fully developed inflow was taken from a
case of DNS for flow transition. The inflow condition is carefully checked with the
velocity profile and ratio of boundary layer thickness, ensuring that it is a fully
developed turbulent flow in order to compare with the wind tunnel test.
