The turbulent boundary layer is a region where both preferential dissipation of energy and the production significant vorticity arises as consequence strong velocity gradients. Previous work has shown that, following Reynolds decomposition, purely fluctuating component enstrophy dominant term. Near wall this varies in complex manner with height. In study, we additionally decompose strain rate terms into normal non-normal components using Schur decomposition are able to explain all these features contributions at different heights from constituents involving combinations quantities. What surprising about our results while mean shear action larger-scale structures should that effects over-riding importance wall, most important individual term involves transverse direction. part, because correlation between axis, but it also case negative mean. Hence, local orthogonal direction plays crucial role amplifying yet have developed component. These conclusions support emphasis control literature on wall.
