Abstract-
The mean energy cascade from large eddies to small eddies is a
concept firmly rooted in homogeneous turbulence. Inhomogeneous
turbulence offers a richer picture in which energy is produced near
boundaries in small eddies that grow as they are transported in
physical space to quasi-homogeneous regions where eddy breakdown
cascades the energy through wavenumber space to small,
quasi-homogeneously distributed scales. An unexpected analogy exists
between the scale growth in wall turbulence and turbulent thermal
convection.
