Summary
A perturbation method based on a simultaneous expansion for primary and secondary modes of instability is used to study the flow field in the later stages of transition. Results of the analysis are in good agreement with experimental data for amplitudes in excess of 5% that cause immediate breakdown. Threshold conditions for sustained growth of subharmonic modes past branch II are calculated. These conditions are presented both in terms of branch II amplitudes and initial amplitudes.
