Lighthill's mechanism and vorticity cascade in the logarithmic layer of wall turbulence
Samvit Kumar, Simon Toedtli, Tamer A. Zaki +1
We investigate Lighthill's proposed turbulent mechanism for near-wall concentration of spanwise vorticity by calculating mean flows conditioned on motion away from or toward the wa…

Spatio-temporal characterization of nonlinear forcing and response in turbulent channel flow
Yuting Huang, Simon S. Toedtli, Gregory P. Chini +1
The quadratic convection term in the incompressible Navier-Stokes equations is considered as a nonlinear forcing to the linear resolvent operator, and it is studied in the Fourier…
