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 \(Re_\theta = 7500\) or \(Re_\tau = 2300\). 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 \(\mathrm{y}^+ = 100\), but only local axisymmetry provides a reasonable estimate close to the wall.
