  We present a unique method for solving for the Reynolds stress in turbulent
canonical flows, which is based on momentum balance for a control volume moving
at the local mean velocity. Comparisons with experimental and computational
data in simple geometries show quite good agreement. An alternate picture for
the turbulence momentum transport is offered, based on the closed-form
expression for the Reynolds stress. The turbulence momentum balance is verified
using DNS data. This approach has potential applications in aerodynamics, and
also represents a possible method for determining the Reynolds stress in more
complex flows.
