Abstract: Abstract We study the behaviour of the streamwise velocity variance in turbulent wall-bounded flows using a direct numerical simulation (DNS) database of pipe flow up to friction Reynolds number ${{Re}}_{\tau } \approx 12000$. The analysis… read more here.

Abstract: In this paper, we present a multiscale characterization of the streamwise velocity of a turbulent channel flow. We study the second and fourth order structure functions and the flatness for scales ranging from the dissipative… read more here.
