Abstract:
We investigate the statistical properties of so called streamline segments in a turbulent channel flow with one plane and one wavy wall. We give a short overview on the concept of streamline segments and recent results in description and modelling in this field. Finally, we show the length distribution and conditional moments of streamline segments in the wavy channel flow and compare the statistics to those in homogeneous isotropic turbulence.
