Outer-layer similarity in the presence of a practical rough-wall topography

  title={Outer-layer similarity in the presence of a practical rough-wall topography},
  author={Yanqing Wu and K. T. Christensena},
High-resolution particle image velocimetry measurements are made in the streamwise–wall-normal plane of a zero-pressure-gradient turbulent boundary layer over smooth and rough walls at Re 13000. The roughness considered herein is replicated from a surface scan of a turbine blade damaged by deposition of foreign materials and its topography is highly irregular and contains a broad range of topographical scales. Two physical scalings of the same roughness topography are considered, yielding two… CONTINUE READING
