Technical Notes


Possible corrections for measured spatial velocity derivatives have been inferred from a direct numerical simulation database for a fully developed turbulent channel flow. The magnitude of the correction depends much less on the distance from the wall for derivatives in the spanwise direction than for those in the wall-normal direction. Corrections based on local isotropy are better approximations for spanwise derivatives than for wall-normal derivatives.
