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).

Large Eddy Simulation

Defence Science Journal, 2010
Large eddy simulation (LES) is an emerging technique for obtaining an approximation to turbulent flow fields It is an improvement over the widely prevalent practice of obtaining means of turbulent flows when the flow has large scale, low frequency, unsteadiness An introduction to the method, its general formulation, and the more common modelling for ...

Catalytically Enhanced Near Room‐Temperature Hydrogen Sensing Using Pd‐ZnO Colloidal Crystals

Advanced Functional Materials, EarlyView.
Pd‐decorated ZnO colloidal crystal monolayers demonstrate excellent performance across a wide hydrogen concentration range at 33°C, with high selectivity and reproducible device fabrication. The sensors show strong responses even at low‐ppm H2 concentrations and an ultra‐low detection limit of 82 ppb, indicating their suitability for diverse hydrogen ...

Deep Learning for Subgrid‐Scale Turbulence Modeling in Large‐Eddy Simulations of the Convective Atmospheric Boundary Layer

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.

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy

Advanced Healthcare Materials, EarlyView.
Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.
