Query: Inner/Outer Ratio Similarity Scaling for 2-D Wall-bounded Turbulent
  Flows   The turbulent boundary layer scaling parameters for the velocity profile are
usually associated with either the inner viscous region or the outer boundary
layer region. It has been a long-held view that complete similarity of the
velocity profile can only occur if the inner and outer region scaling
parameters change proportionally as one moves from station to station along the
wall. However, it appears that complete similarity is not possible for the
wall-bounded turbulent boundary layer. Hence, the outer/inner ratio would seem
to be of little use. However, recent revelations revive the need for
identifying likely experimental datasets that display outer region similarity.
It is our contention that likely datasets can be identified by finding datasets
in which the inner-outer thickness ratio is almost constant. This inner-outer
thickness ratio is usually associated with the Rotta scaling ratio.
Unfortunately, the Rotta ratio proportional change condition has never been
shown to be a similarity requirement. In contrast, we show that a recently
developed thickness ratio based on the integral moment method must change
proportionately from station to station if similarity is present.
