| Abstract/Summary |
The electrodiffusion method has been used to investigate the structure of near-wall turbulence. Two techniques recently used for fabrication of the multi-segment electrodiffusion probes are presented. The measurements performed in two experimental channel flows have demonstrated the application of such directionally sensitive probes under unsteady flow conditions. The traditional three-segment electrode provided valuable information on the recirculating flow structure behind a backward-facing step. The microelectrodes prepared by the new photolithography technique have been used to assess the influence of high polymer additives on spatial and temporal correlations of the flow fluctuations close to the wall.
