Interactions within the turbulent boundary layer at high Reynolds number
Simultaneous streamwise velocity measurements across the vertical direction obtained in the atmospheric surface layer (Reτ 5 × 10) under near thermally neutral conditions are used to outline and quantify interactions between the scales of turbulence, from the very-large-scale motions to the dissipative scales. Results from conditioned spectra, joint probability density functions and conditional...
متن کاملObservations on High Reynolds Number Turbulent Boundary Layer Measurements
An experimental study that examines spatial resolution effects on the measured streamwise velocity component is presented. Normal hot-wire measurements for mean flow velocity profiles, streamwise turbulence intensity profiles in addition to their respective spectra at different levels within the turbulent boundary layers will be presented. Measurements were carried out at Reynolds number based ...

متن کاملMeasurements of streamwise and spanwise fluctuating velocity components in a high Reynolds number turbulent boundary layer
Measurements of the streamwise and spanwise fluctuating velocity components are obtained in a high Reynolds number turbulent boundary layer using custom made sub-miniature hot wires. These measurements are made over a range of Reynolds numbers from Reτ ≈ 3,000 to Reτ ≈ 10,500, but at fixed unit Reynolds number U∞/ν (Reτ = δUτ/ν; where ν is the kinematic viscosity, Uτ is the friction velocity an...
