Effect of Successive Suction on the Near-Wall Turbulence Structure

ABSTRACT

The effects of successive suction on the near-wall turbulence structure have been examined in a wall bounded boundary layer through the measurements of turbulent quantities, production and diffusion terms of the turbulent kinetic energy equation. The result indicates that double suction shows a better alteration of the near-wall turbulent structures than a single suction. Turbulent kinetic energy production is significantly reduced and the effect is enhanced by double suction downstream of the second strip. There is a gain of turbulent kinetic energy by diffusion in the near-wall region for both cases of suction relative to those of zero-suction.
