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…

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…

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…
