LDV Measurement Near a Rough Surface for a Turbulent Boundary Layer,w momentum flux and Reynolds shear stress estimated in the cavity between the roughness elements. The integral length scales of the mean flow momentum flux and the Reynolds shear stress contribute 30% and 70% respectively to the moment centroid.

An Experimental Study of a Turbulent Wall Jet on Smooth and Rough Surfaces,hickness of the inner layer increases. Profile fitting was used to estimate the friction velocity. The results showed that at ..≈ 3, 500 the roughness caused an increase of about 30% in the skin friction coefficient.

,A High Reynolds Number Turbulent Boundary Layer with Regular ‘Braille-Type’ Roughness,wed an unexpected result: large-scale structures are significantly influenced by the roughness elements, despite the elements being ∼ 2 orders of magnitude smaller in size than these large-scale motions. This result excites the possibility of manipulating large-scale flow features with tiny protrusions.

Much research has concentratedon ows over smooth walls since these are simpler from experimental, numerical and theoretical standpoints. The ow over rough walls has still received considerable attention but progress has necessarilybeenslower.Perhapsthemostesse

Turbulence in Pipe Flows with Small Relative Roughness,itional and fully rough flow regimes, the streamwise Reynolds normal stress in the outer layer was found to saturate at a maximum value and did not increase in the same manner as observed for smooth pipes.

Turbulent Flow Over Urban-Type Roughness Using PIV,d Reynolds stresses across the entire boundary layer were examined and compared with that of a smooth wall. Spatial correlation data, extracted from the PIV images were used to provide information about eddy structures and comparisons have been made with previous data for the uniform cube surface.
