Stratification, turbulence organization, and pressure-strain effects on surface-layer turbulence anisotropy
Ivana Stiperski, Gabriel G. Katul, Elie Bou-Zeid +1
At large scales, the Reynolds stress tensor exhibits notable anisotropy, a key feature of all wall-bounded turbulent flows. Yet, how the drivers of this anisotropy evolve with shea…
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…
Asymptotic limits of the attached eddy model derived from an adiabatic atmosphere
Yue Qin, Gabriel G. Katul, Heping Liu +1
The attached-eddy model (AEM) predicts mean velocity and streamwise velocity variance profiles that follow a logarithmic shape in the overlap region of high Reynolds number wall-bo…
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…
Revisiting a drag partition model for canopy-like roughness elements
Elia Buono, Gabriel G. Katul, Davide Vettori +2
Turbulent flows over a large surface area (S) covered by n obstacles experience an overall drag due to the presence of the ground and the protruding obstacles into the flow. The dr…
