On the large-scale vertical velocity intermittency of turbulent wall flows
Tirtha Banerjee, Elia Buono, Costantino Manes +6
Large-scale intermittency in the vertical velocity (LSI) has received significant attention in studies of coherent structures and their detection using data-driven approaches. Howe…
On the wall-normal velocity variance in canonical wall-bounded turbulence
Michael Heisel, Rahul Deshpande, Gabriel G. Katul
The variance and spectra of wall-normal velocities are investigated for direct numerical simulations of turbulent flow in a channel, pipe, and zero-pressure-gradient boundary layer…
The vertical velocity skewness in the atmospheric boundary layer without buoyancy and Coriolis effects
Elia Buono, Gabriel Katul, Michael Heisel +4
One of the main statistical features of near-neutral atmospheric boundary layer (ABL) turbulence is the positive vertical velocity skewness above the roughness sublayer or t…
The vertical-velocity skewness in the inertial sublayer of turbulent wall flows
Elia Buono, Gabriel Katul, Michael Heisel +4
We provide empirical evidence that within the inertial sub layer of adiabatic turbulent flows over smooth walls, the skewness of the vertical velocity component displays uni…
