For a two-dimensional flow (w = 0)over a flat plate, the thickness of turbulent boundary layer is assumed to be much smaller than the axial length and the order of magnitude analysis may be applied. As a consequence, the following inferences are drawn:

-
(33.9) (33.10)
- A comparison of Eq. (33.10) with laminar boundary layer Eq. (23.10) depicts that: u, v and p are replaced by the time average values
and
,and laminar viscous force per unit volume
is replaced by
where
is the laminar shear stress and
is the turbulent shear stress.
