eng Abstract:
Contribution poses flow characteristics of symmetric very rough turbulent layer in wind-tunnel Wotan in Hamburg. Measurement was conducted using 2-D component LDA with high temporal resolution. Requirements for generating a top quality boundary layer with consistent parameters that follow up-to-date science of physical modeling are described and explained. Main attention was focused on linkage between integral length scale and turbulence intensity Ix and Iz according to guideline VDI.
