متن کاملTurbulent Streamwise Edge Effects in the Boundary Layer on a Flat Plate Finite Aspect Ratio
A detailed investigation of the turbulent boundary layer on a flat plate of finite aspect ratio at zero incidence has been made, incorporating measurements of mean velocity profiles and skin friction over one surface of the plate. Skin friction was measured using Prof. Preston's surface-tube technique with the N.P.L. calibration, and this is justified by comparison with the measured momentum de...
متن کاملRegions of Uniform Streamwise Momentum in Turbulent Boundary Layers
This study investigates the presence of zones of uniform streamwise momentum (or UMZs) across a range of Reynolds numbers in turbulent boundary layers, spanning more than an order of magnitude (Reτ ≈ 10 3 − 10). A rigorous examination of the identification criteria suggested by Adrian et al. [1] is presented, and then employed to show that a zonal-like structure is prevalent in all datasets exa...
متن کاملScaling of inner and outer regions for flat plate boundary layers
A new view of the scaling of the streamwise turbulence intensity profile is proposed for the zero pressure gradient turbulent boundary layer. The method is based on the scale decomposed streamwise velocity component, separated into a smalland a large-scale contribution using a wavelength pass-filter. This enables us to understand how large and small scale motions affect the streamwise turbulenc...
متن کاملEffect of Flat Plate Leading Edge Pattern on Structure of Streamwise Vortices Generated in Its Boundary Layer
The use of leading edge with different geometrical patterns will affect the development of boundary layer flow on a flat plate and its heat transfer properties. In this work, the effects of three patterns namely saw-tooth, semicircular and slots with same wavelength and amplitude were examined. The experiments were carried out for Reynolds number based on wavelength of patterns ranging from 154...
