A framework for studying the effect of compliant surfaces on wall turbulence
M. Luhar, A. S. Sharma, B. J. McKeon
This paper extends the resolvent formulation proposed by McKeon & Sharma (2010) to consider turbulence-compliant wall interactions. Under this formulation, the turbulent velocity f…
A foundation for analytical developments in the logarithmic region of turbulent channels
Rashad Moarref, Ati S. Sharma, Joel A. Tropp +1
An analytical framework for studying the logarithmic region of turbulent channels is formulated. We build on recent findings (Moarref et al., J. Fluid Mech., 734, 2013) that the ve…
A low-order decomposition of turbulent channel flow via resolvent analysis and convex optimization
R. Moarref, M. R. Jovanovic, J. A. Tropp +2
We combine resolvent-mode decomposition with techniques from convex optimization to optimally approximate velocity spectra in a turbulent channel. The velocity is expressed as a we…
