SUMMARY:Wall-bounded turbulence: Experiments and perspectives - Ivan Marus

DESCRIPTION:In this talk we survey experimental issues in the field of wal
 l turbulence. Wall-bounded turbulent flows\, by their definition\, are cha
 racterised by the close proximity of a surface (or &ldquo\;wall&rdquo\;). 
 This results in a flow that is highly anisotropic\, making measurements\, 
 particularly near the surface\, highly challenging to undertake. This is f
 urther exacerbated as the Reynolds number increases to large values\, such
  as those encountered in many important practical applications. The past d
 ecade or so has seen significant advances in our capabilities to make high
 -fidelity measurements of the three components in velocity and vorticity\,
  in space and time\, and of the wall-shear stress in high Reynolds number 
 wall-turbulence. This progress has resulted from both the development of n
 ew high Reynolds number facilities and advances in measurement techniques.
  Findings from the experiments will be discussed and implications for futu
 re work will be considered.
