Parameter investigation for urban surface‐energy balance: A large‐eddy simulation study

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Large eddy simulation modelling is used to investigate the variation in surface‐energy balance (SEB) across an ensemble of morphometrically identical urban geometries. The geometries have the same plan‐area fraction, vegetated fraction, and frontal‐area index, but are unique in terms of building and green‐space layout.

A Novel Methodology for the Automatic Decomposition of HAWT Wakes With K‐Means Clustering

Wind Energy, Volume 28, Issue 7, July 2025.
ABSTRACT This work presents a novel and automatic approach to process data from computational fluid dynamics at runtime, to identify and separate different regions of wind turbine wakes. The methodology is based on partitional clustering, in particular k‐Means, and applied to large eddy simulation (LES) computations of the wake of a DTU‐10‐MW wind ...

Analysis and Modeling of Non-Spherical Particle Motion in a Gas Flow

KONA Powder and Particle Journal, 2022
This paper describes the reviews of the recent works in analysis, modeling, and simulation of the motion of a non-spherical particle. The motion of the non-spherical particles was analyzed in detail by means of a fully resolved direct numerical ...

A Model Intercomparison Study of Aerosol‐Cloud‐Turbulence Interactions in a Cloud Chamber: 1. Model Results

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 7, July 2025.
Abstract This study presents the first model intercomparison of aerosol‐cloud‐turbulence interactions in a controlled cloudy Rayleigh‐Bénard Convection chamber environment, utilizing the Pi Chamber at Michigan Technological University. We analyzed simulated cloud chamber‐averaged statistics of microphysics and thermodynamics in a warm‐phase, cloudy ...

Effect of Splitter Angles on Characteristics of Mixing Layer Flow: A Numerical Study [PDF]

Journal of Applied and Computational Mechanics
This study investigates the effect of splitter angles on the aerodynamic flow of two free streams under incompressible conditions. The angle of the splitter is changed from 0 to 40° to simulate different wake structures on the slant.

Factors Controlling Precipitation Onset and Maintenance: Inferences From Large Eddy Simulations of Two Afternoon Deep Convective Regimes Over Amazon

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract To investigate the environmental factors controlling the onset and maintenance of afternoon precipitation over tropical rainforests, two contrasting cases are created for large eddy simulations (LES) using GoAmazon observations: one features a single‐pulse rain dissipating quickly in earlier afternoon, while the other shows double pulses ...

Monitoring Point of External Wind Velocity Around Building Roof Top for Natural Ventilation Control

JAPAN ARCHITECTURAL REVIEW, Volume 8, Issue 1, January–December 2025.
ABSTRACT In order to measure external approaching wind velocity and direction for controlling natural ventilation (NV), anemometers are often installed at the roof top of mid‐ to high‐rise buildings. However, due to the complex flow field around roof top caused by separation flow, the accuracy of the measurement is not well‐known.

Le lait, le sperme, le dos. Et le sang ? [PDF]

Cahiers d'études africaines, 2001
Une institution comme celle de la parente de lait qui a sa source dans le Coran, se retrouve dans de nombreuses societes musulmanes. De la parente de lait, tres courante dans la societe maure, la logique des substances corporelles rend compte, et ceci a partir de la theorie locale de la genese physiologique des enfants.
