|Titolo:||Skin friction Correlation for Real Roughened Surfaces|
|Data di pubblicazione:||2006|
|Abstract:||Measurements of the flow field around flat plates with different surface roughness are presented. The effects of surface roughness on boundary layer features are analyzed through scaled facsimiles of real turbine blades. Four rough plates and a smooth plate were tested at different high Reynolds number conditions. Velocity profiles and boundary layer features are presented for all plates. Skin friction coefficient is estimated and laws of the wall are proposed for different roughness profiles. Surface texture experimental data are analyzed and the most representative roughness parameters are underlined; moreover, a correlation between technical and real surface roughness is proposed.|
