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…
Seeing through water: diffuse image-based depth measurements in three-dimensional dam-break flows
Elia Buono, Roberto Bosio, Andrea Cagninei +1
In this work we present a dedicated experimental facility and an image-based method for measuring water depth in a radially spreading dam-break wave propagating over a horizontal p…
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…
