Lattice eddy simulation of turbulent flows
Jinglei Xu, Qi Li, Xianxu Yuan +3
Kolmogorov's (1941) theory of self-similarity implies the universality of small-scale eddies, and holds promise for a universal sub-grid scale model for large eddy simulation. The…
On the logarithmic profile of temperature in the atmospheric convective boundary layers
Yu Cheng, Qi Li, Pierre Gentine
Wall-bounded turbulent flows are widely observed in natural and engineering systems, such as air flows near the Earth's surface, water flows in rivers, and flows around a car or a…
Deep learning for subgrid-scale turbulence modeling in large-eddy simulations of the atmospheric boundary layer
Yu Cheng, Marco Giometto, Pit Kauffmann +7
In large-eddy simulations, subgrid-scale (SGS) processes are parameterized as a function of filtered grid-scale variables. First-order, algebraic SGS models are based on the eddy-v…
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…
On the Power-law Scaling of Turbulence Cospectra Part 1: Stably Stratified Atmospheric Boundary Layer
Yu Cheng, Qi Li, Andrey Grachev +3
Turbulent fluxes in the atmospheric surface layer are key input for the prediction of weather, hydrology, and carbon dioxide concentration. In numerical modelling of turbulent flux…
Turbulence Spectra in the Stable Atmospheric Boundary Layer
Yu Cheng, Qi Li, Stefania Argentini +2
Stratification can cause turbulence spectra to deviate from Kolmogorov's isotropic -5/3 power-law scaling in the universal equilibrium range at high Reynolds numbers. However, a co…
