Prediction of Compliant Wall Drag Reduction

ISBN: 9781724680730
Category :
Languages : en
Pages : 32
Book Description
A numerical model of turbulent boundary layer flows over compliant walls was investigated. The model is based on Burton's observation that outer flow structures in turbulent boundary layers produce large scale pressure fluctuations near the wall. The results of calculations indicate that certain small wavelength wall motions can have a significant effect upon the stability of turbulent boundary layers. Orszag, S. A.

Behavior of Turbulent Boundary Layers on Curved Convex Walls
Author: Hans Schmidbauer
Publisher:
ISBN:
Category : Mathematics
Languages : en
Pages : 570
Book Description
The system of linear differential equations which indicated the approach of separation and the so-called "boundary-layer thickness" by Gruschwitz is extended in this report to include the case where the friction layer is subject to centrifugal forces. Evaluation of the data yields a strong functional dependence of the momentum change and wall drag on the boundary-layer thickness radius of curvature ratio for the wall. It is further shown that the transition from laminar to turbulent flow occurs at somewhat higher Reynolds Numbers at the convex wall than at the flat plate, due to the stabilizing effect of the centrifugal forces.
