Interaction of forced Orr-Sommerfeld and Squire modes in a low-order representation of turbulent channel flow
Ryan M. McMullen, Kevin Rosenberg, Beverley J. McKeon
A resolvent-based reduced-order representation is used to capture time-averaged second-order statistics in turbulent channel flow. The recently-proposed decomposition of the resolv…
The role of parasitic modes in nonlinear closure via the resolvent feedback loop
Kevin Rosenberg, Sean Symon, Beverley J. McKeon
We use the feedback loop of McKeon \& Sharma (2010), where the nonlinear term in the Navier-Stokes equations is treated as an intrinsic forcing of the linear resolvent operator, to…
On non-normality and classification of amplification mechanisms in stability and resolvent analysis
Sean Symon, Kevin Rosenberg, Scott T. M. Dawson +1
We seek to quantify non-normality of the most amplified resolvent modes and predict their features based on the characteristics of the base or mean velocity profile. A 2-by-2 model…
Nonlinear forcing in the resolvent analysis of exact coherent states of the Navier-Stokes equations
Kevin Rosenberg, Beverley J. McKeon
The resolvent analysis of McKeon & Sharma (2010) recasts the Navier-Stokes equations into an input/output form in which the nonlinear term is treated as a forcing that acts upon th…
Experimental Interpretation of Interfacial Separation and Squeezing Pressure
C. Yang, B. N. J. Persson, J. Israelachvili +1
The logarithmic relation between interfacial separation and squeezing pressure between randomly rough surfaces, has been predicted by both theory and experiment. However, the exper…
