Measurements of Attached and Separated Turbulent Flows in the Trailing-Edge Regions of Airfoils,
Abstract
Measurements of incompressible turbulent flows near the trailing edge have been made in three different configurations: (1) a conventional airfoil at zero incidence with near-symmetric flow, (2) a supercritical airfoil at an angle of attack of 4 degrees with strongly asymmetric but attached flow, and (3) supercritical airfoil at a high angle of attack of 12 degrees with upper-surface boundary-layer separation. Mean flow and turbulence including three Reynolds stress components, four triple correlations and some frequency spectra were obtained using pressure and hot-wire probes as well as a laser-doppler velocimeter. Selected results are presented to show the features of viscous-inviscid interaction and characteristics of turbulence in the trailing-edge region. (Author)
