Abstract

An experiment was performed in the LML boundary layer facility to determine all of the derivative moments needed to estimate the dissipation. The Reynolds number was Reθ = 7500 or Reτ = 2300. A detailed analysis of the errors in derivative measurements was carried out, as well as applying and using consistency checks derived from the continuity equation and a local homogeneity hypothesis. Local homogeneity estimates of the dissipation are accurate everywhere within a few percent. Both local axisymmetry and local isotropy work almost as well outside of y+ = 100, but only local axisymmetry provides a reasonable estimate close to the wall.
