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.

Discretization error dominance over subgrid terms in large eddy simulation of compressible shear layers in 2D [PDF]

, 1994
Second- and fourth-order-accurate spatial discretization methods give rise to discretization errors which are large than the corresponding subgrid terms in large eddy simulation of compressible shear layers in 2D, if the ratio between the filter width ...

Large eddy simulation of radiation fog: impact of dynamics on the fog life cycle

, 2017
. Large eddy simulations (LESs) of a radiation fog event occurring during the ParisFog experiment are studied with a view to analyse the impact of the dynamics of the boundary layer on the fog life cycle.

Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This work demonstrates the design, fabrication, and the first‐time test of a 2D photonic crystal surface for photonic resonator absorption microscopy. The designed surface uniformly enhances electromagnetic near fields, achieving > 100% improved detecting uniformity for surface‐captured AuNPs from a blocking biosensor assay aimed for detecting SARS‐CoV‐

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 ...

Large Eddy Simulation of Turbulent Channel Flows by the Rational LES Model

, 2002
The rational large eddy simulation (RLES) model is applied to turbulent channel flows. This approximate deconvolution model is based on a rational (subdiagonal Pade') approximation of the Fourier transform of the Gaussian filter and is proposed as an ...

Large Eddy Simulation of Vented Deflagration [PDF]

, 2013
In order to understand gas explosion phenomena in industrial buildings, a reduced-scale vented combustion 6 chamber is investigated numerically. In this configuration, a flame is ignited in an initially quiescent flammable mixture and 7 propagates past

A Review on Microreactor Design for Effective Fischer–Tropsch Process Intensification

Advanced Materials Technologies, EarlyView.
Design strategies for effective Fischer–Tropsch process intensification are summarized based on experimental and simulation experiences. Recommendations for catalyst loading of packed‐bed and wash‐coated microchannel, microtube, micromonolith, and microstructured reactors are discussed.

A Virtual Clinical Trial of Psychedelics to Treat Patients With Disorders of Consciousness

Advanced Science, EarlyView.
Disorders of consciousness after severe brain injury are marked by reduced complexity of brain activity and limited treatment options. Using personalized whole‐brain models, this study shows that simulated lysergic acid diethylamide (LSD) and psilocybin shift patient brain dynamics closer to criticality.

Rain Evaporation, Snow Melt, and Entrainment at the Heart of Water Vapor Isotopic Variations in the Tropical Troposphere, According to Large‐Eddy Simulations and a Two‐Column Model

Journal of Advances in Modeling Earth Systems, 2021
We aim at developing a simple model as an interpretative framework for the water vapor isotopic variations in the tropical troposphere over the ocean. We use large‐eddy simulations of disorganized convection in radiative‐convective equilibrium to justify
