Abstract

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.

Keywords: Boundary layer thickness, Fully developed turbulent flow, High order DNS, Velocity profile.
