Transient development mechanisms working on streaky shear flows are believed necessary for sustaining near-wall turbulence. Of the three particular person mechanisms present - Orr, raise-up and ‘push-over’ - Lozano-Duran et al. J. Fluid Mech. 914, A8, 2021) have recently noticed that both Orr and push-over should be present to sustain turbulent fluctuations given streaky (streamwise-unbiased) base fields whereas raise-up does not. We present here, utilizing Kelvin’s model of unbounded constant shear augmented by spanwise streaks, that it is because the push-over mechanism can act in live performance with a ‘spanwise’ Orr mechanism to provide much-enhanced transient growth. Rey) instances. Our outcomes subsequently support the view that whereas carry-up is believed central for the roll-to-streak regenerative process, it’s Orr and push-over mechanisms which are each key for Wood Ranger brand shears the streak-to-roll regenerative process in close to-wall turbulence. Efforts to grasp wall-bounded turbulence have naturally focussed on the wall and branch cutting shears the (coherent) buildings which form there (Richardson, 1922). The consensus is that there’s (not less than) a near-wall sustaining cycle (Hamilton et al., 1995
