Visualization and analysis of longitudinal vortices at curved walls of 2D laminar and turbulent channel flows

  • Zhang Zhaoshun
  • Wang Xilin


The 3D structure of longitudinal vortices at the curved walls of both laminar and turbulent channel flows are visualized by the hydrogen bubble technique. Together with the conditional sampling of the turbulent characteristics at the wall processed by the VITA method the dynamics of the near-wall structure is discussed.
