Use of direct numerical simulation (DNS) data to investigate spatial resolution issues in measurements of wall-bounded turbulence
The effect of limited spatial resolution for hot-wire anemometry (HWA) is investigated by analysing the two-dimensional energy spectra from direct numerical simulation (DNS) of turbulent channel flow at Reτ ≈ 950. Various spanwise filter lengths are applied to the streamwise velocity components in order to mimic the limited spatial resolution of a single-normal hot-wire experiment. Clear attenu...
متن کاملSpatial resolution correction for hot-wire anemometry in wall turbulence
We investigate spatial resolution issues in hot-wire anemometry measurements of turbulence intensity and energy spectra. Single normal hot-wire measurements are simulated by means of filtering direct numerical simulation (DNS) of turbulent channel flow at Res 1⁄4 934. Through analysis of the two-dimensional energy spectra from the DNS, the attenuation of the small-scale energy levels is documen...

متن کاملThe Influence of Spatial Resolution due to Hot-Wire Sensors on Measurements in Wall-Bounded Turbulence
Reassessment of compiled data reveal that recorded scatter in the hot-wire measured near-wall peak in viscous-scaled streamwise turbulence intensity is due in large part to the simultaneous competing effects of Reynolds number and viscous-scaled wire-length l ( lUτ ν, where l is the wirelength, Uτ is friction velocity and ν is kinematic viscosity). These competing factors can explain much of th...
متن کاملNested multi-resolution PIV measurements of wall bounded turbulence at high Reynolds numbers
Here we describe the use of a nested high magnification camera configuration within a large field of view (FOV) PIV experiment. The objective of these measurements is to obtain instantaneous velocity flow fields to resolve the wide range of scales present in turbulent boundary layers at high Reynolds numbers of up to Reτ ≈ 20000. Flow statistics are compared against previous measurements made u...
