Stable stratification enhances transient growth in streaky shear flows
Will Oxley, Rich Kerswell
Recent work has found that the well-known `lift-up' mechanism is not important for, and may even inhibit, the transient growth possible on streaky wall-bounded shear flows which is…

Transient Growth in Streaky Unbounded Shear Flow: A symbiosis of Orr and Push-over mechanisms
W. Oxley, R. R. Kerswell
Transient growth mechanisms operating on streaky shear flows are believed important for sustaining near-wall turbulence. Of the three individual mechanisms present - Orr, lift-up a…
