Study on the Turbulence Structure and Turbulence Model of Turbulent Boundary Layer with a Suction

Abstract

Experimental and theoretical analyses for turbulent boundary layers with and without adverse pressure gradient and suction through a porous flat plate are described in this paper. From an experimental investigation of velocity profile, turbulent energy, Reynolds shear stress, space-time correlation and energy spectra of these boundary layers, the influences of adverse pressure gradient and suction on the characteristics of turbulent boundary layer are discussed. Moreover, experimental data are compared with the results of numerical calculations on the assumptions of zero-, one- and two-equation models. And the applicabilities of these models to the turbulent boundary layer with suction are discussed.
