Turbulent skin-friction reduction by wavy surfaces
Sacha Ghebali, Sergei I. Chernyshenko, Michael A. Leschziner
Direct numerical simulations of fully-developed turbulent channel flows with wavy walls are undertaken. The wavy walls, skewed with respect to the mean flow direction, are introduc…

Relationship between the methods of bounding time averages
Sergei Chernyshenko
The problem of finding bounds of time-averaged characteristics of dynamical systems, such as the bound on the mean energy dissipation rate in a turbulent flow governed by incompres…
