    transition evolution with a separated boundary layer, for paths under wakes and in between wakes, can be similar to the evolution under a statistically steady mean flow was further demonstrated by Schobeiri et al. [32,33] for unsteady wake passages from cylindrical rods along the suction side of.   SEE parent document record, "Minnowbrook II Workshop on Boundary Layer Transition in Turbomachines"; p. ; NASA/CP Financial Sponsor: NASA Lewis Research Center; Cleveland, OH United States.

      The workshop was focused on physical understanding the late stage (final breakdown) boundary layer transition, separation, and effects of unsteady wakes with the specific goal of contributing to engineering application of improving design codes for turbomachinery. Transition to chaos and basins of attraction in the impact oscillator.

[Control of oscillations and chaos. International conference /1./.

      With D = 10%, the boundary layer appears to be close to reattaching at t/T = , , and at Stations 3 through 6 respectively. With D = 50%, reattachment occurs at about the same phases as in the D = 10% case. The boundary layer then starts to re-separate, but at Stations 5 and 6 it reattaches again about half a cycle later. The book provides senior undergraduate students, graduate students and engineers in the turbomachinery industry with a solid background of turbomachinery flow physics and performance fundamentals that are essential for understanding turbomachinery performance and flow complexes.

The boundary layer subsequently relaxes back to its naturally separated state.

This relaxation occurs on a timescale which is five to six times longer than the original attachment due to the starting vortex.

Phase-locked boundary layer measurements taken at various stations along the blade chord illustrate this slow relaxation phenomenon. R Narasimha: "Post workshop summary" Proc. Minnowbrook II Workshop on Boundary Layer Transition in Turbomachines (Eds.
