A statistical state dynamics approach to wall-turbulence
Brian F. Farrell, Dennice F. Gayme, Petros J. Ioannou
This paper reviews results from the study of wall-bounded turbulent flows using statistical state dynamics (SSD) that demonstrate the benefits of adopting this perspective for unde…
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…
