Query: Turbulence Momentum Transport and Prediction of the Reynolds Stress in
  Canonical Flows   We present a unique method for solving for the Reynolds stress in turbulent
canonical flows, based on the momentum balance for a control volume moving at
the local mean velocity. A differential transform converts this momentum
balance to a solvable form. Comparisons with experimental and computational
data in simple geometries show quite good agreements. An alternate picture for
the turbulence momentum transport is offered, as verified with data, where the
turbulence momentum is transported by the mean velocity while being dissipated
by viscosity. The net momentum transport is the Reynolds stress. This
turbulence momentum balance is verified using DNS and experimental data.
Implications of this work are that the Reynolds stress can be written
explicitly in terms of basic turbulence parameters in a simple form, derived
from pure fluid physics, and that potential exists for applications of this
concept to more complex turbulent flows.
