The instability of streaks in near-wall turbulence

  title={The instability of streaks in near-wall turbulence},
  author={By G. Kawahara and Javier Bustos Jimenez and Markus Uhlmann and Alfredo Pinelli},
Several aspects of the self-sustaining mechanism of near-wall turbulence have been studied recently (see Jiménez & Moin 1991; Hamilton, Kim & Waleffe 1995; Waleffe 1997; Schoppa & Hussain 1997; Jiménez & Pinelli 1998). It is well-known that there are two key structures, streamwise vortices and streaks, in the near-wall region. Streamwise vortices generate streaks through the deformation of the mean flow by their induced cross-flow advection. The streaks, which are nearly uniform in the… CONTINUE READING
