Effect of Wall Suction on Coherent Structures in a Turbulent Boundary Layer

SINOPSIS

An experimental study has been carried out in a turbulent boundary layer subject to concentrated wall suction, applied through a porous wall strip with the view to examine the modification of the coherent structures by suction. The results indicate that active and inactive motions are suppressed by suction as reflected in the significant reduction in the Reynolds stresses and alterations in spectra distributions. These would result in the modification in the coherent structures. The change in the mixing lengths distributions suggests that the near-wall flow dynamics have been altered by suction. The effect of these changes in the near-wall coherent structures increases as the suction rate is increased.
