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…

Contrasts Between Momentum and Scalar Transport Over Very Rough Surfaces
Qi Li, Elie Bou-Zeid
Large-eddy simulations are conducted to contrast momentum and passive scalar transport over large, three-dimensional roughness elements in a turbulent channel flow. Special attenti…
