A Surface Flux Estimation Scheme Accounting for Large‐Eddy Effects for Land Surface Modeling
Geophysical Research Letters, 2022 We propose a surface flux estimation formula to account for large eddy effects by keeping the boundary layer depth the only added parameter. We develop a novel way to evaluate the estimation formula by using a set of independent large eddy simulations ...

A Stochastic Approach for Parameterizing Unresolved Scales in a System with Memory
Journal of Algorithms & Computational Technology, 2009 Complex systems display variability over a broad range of spatial and temporal scales. Some scales are unresolved due to computational limitations. The impact of these unresolved scales on the resolved scales needs to be parameterized or taken into ...

Numerical simulation of flow separation over a backward-facing step with high Reynolds number
Water Science and Engineering, 2019 Large eddy simulation (LES) explicitly calculates the large-scale vortex field and parameterizes the small-scale vortices. In this study, LES and κ-ε models were developed for a specific geometrical configuration of backward-facing step (BFS).

Journal of Advances in Modeling Earth Systems, 2022 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‐viscosity assumption, which does not always hold for turbulence.

Large eddy simulation of film cooling on turbine vane
Journal of Thermal Science and Technology, 2019 Large eddy simulations were performed for film cooling on scaled-up C3X turbine vane at the nominal blowing ratio of M=0.5~1.5, and the Reynolds number, Re=3000, based on the mainstream inlet velocity and hole diameter.

Large Eddy Simulation for Dispersed Bubbly Flows: A Review
International Journal of Chemical Engineering, 2013 Large eddy simulations (LES) of dispersed gas-liquid flows for the prediction of flow patterns and its applications have been reviewed. The published literature in the last ten years has been analysed on a coherent basis, and the present status has been ...
