SUMMARY:How quasi-steady is the modulation of near-wall turbulence by larg
 e-scale structures? - Sergei Chernyshenko (Imperial College London)

DESCRIPTION:Authors: Sergei Chernyshenko and Yunjiu Yang (Imperial College
 )\nThe idea that the near-wall turbulence quasi-steadily adjusts itself to
  the large-scale component of the wall friction\, if formulated in a mathe
 matically rigorous form\, allows nontrivial quantitative predictions. Howe
 ver\, the actual modulation effect is only approximately quasi steady. Thi
 s talk will describe the current state of the theory\, and then focus on t
 he limits of its applicability. A brief review of the theory will be given
 . Applications to all three velocity components will be considered\, and c
 omparisons with direct numerical calculations and experiments will be made
 .
