Description:
Author(s): X. I. A. Yang, C. Meneveau, I. Marusic, and L. Biferale Moment generating functions in wall-bounded flows exhibit power-law scaling in the log region. Interpreted with extended self-similarity, the extent of those scalings extends to the bulk region and the viscosity-affected near-wall region. New findings indicate that the Townsend attached eddy hypothesis can be used to model the flow beyond the log region if we allow the characteristic velocity scale to depend on the wall normal distance.
