Turbulence dissipation is central to many aspects of turbulent flows and its mechanism away from walls is the turbulence cascade. The prevailing turbulence cascade paradigm since 1941 has been Kolmogorov’s equilibrium cascade for locally stationary homogeneous turbulence. Even in such idealized turbulence, however, the cascade cannot be understood and evaluated without taking into account intermittency’s local inhomogeneities and non-stationarities. We therefore concentrate attention to two instances of extreme inhomogeneity/intermittency: the turbulent/non-turbulent interface (TNTI) and the highly inhomogeneous near field of a turbulent wake. In incompressible turbulent flows, there can be no forward cascade without inverse cascade being present too. The TNTI orients the forward cascade in directions around the normal to it and the inverse cascade in directions aligned with its tangent plane. A somehow intermediate cascade regime exists in between. In the very near field of a turbulent wake, where the strong statistical inhomogeneity and non-equilibrium preclude any possibility of applying the Kolmogorov equilibrium cascade theory, an orientation-averaged interscale transfer rate is found to be about constant over a significant range of scales and this constant even close to the turbulence dissipation rate. An analysis of this simple self-similar balance in this complex non-homogeneous, non-isotropic and non-stationary turbulent flow reveals that turbulence inhomogeneity and the presence of large-scale coherent structures contribute to making it possible.
