Statistical State Dynamics of Vertically Sheared Horizontal Flows in Two-Dimensional Stratified Turbulence
Joseph G. Fitzgerald, Brian F. Farrell
Simulations of strongly stratified turbulence often exhibit coherent large-scale structures called vertically sheared horizontal flows (VSHFs). VSHFs emerge in both two-dimensional…
Statistical state dynamics based theory for the formation and equilibration of Saturn's north polar jet
Brian F. Farrell, Petros J. Ioannou
Coherent jets with most of the kinetic energy of the flow are common in atmospheric turbulence. In the gaseous planets these jets are maintained by incoherent turbulence excited by…
Statistical state dynamics-based analysis of the physical mechanisms sustaining and regulating turbulence in Couette flow
Brian F. Farrell, Petros J. Ioannou
This paper describes a study of the self-sustaining process in wall-turbulence based on a second order statistical state dynamics (SSD) model of Couette flow. SSD models with this…
Instability of the roll/streak structure induced by free-stream turbulence in pre-transitional Couette flow
Brian F. Farrell, Petros J. Ioannou, Marios-Andreas Nikolaidis
Although the roll/streak structure is ubiquitous in pre-transitional wall-bounded shear flow, this structure is linearly stable if the idealization of laminar flow is made. Lacking…
