Unsteady behaviour of opposite impinging jets interaction in crossflow

Nihon Kikai Gakkai ronbunshu, 2016
A mixing of fuel with air in jet engine is studied by analyzing unsteady turbulent flow in a simplified flow channel which consists of the opposed jets in a cross-flow.

Study on effects of wall mass transfer condition for measurement of geometry factor

Nihon Kikai Gakkai ronbunshu, 2016
It is necessary to evaluate the geometry factor for predicting the flow accelerated corrosion (FAC) in the plant piping. Geometry factor is defined as the ratio of the wall mass transfer coefficient in the piping systems (such as orifices, elbows) to ...

Sensitivity of flower trade‐wind cloud organisation to mesoscale atmospheric heterogeneities

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 777, April 2026 Part B.
Trade‐wind cloud organisation is insensitive to dynamical and thermal heterogeneities but very sensitive to humidity mesoscale heterogeneities, especially in the cloud layer, where they form moist patches, and not in the sub‐cloud layer. Clouds and rain develop in moist patches, then cold pools develop progressively, initiating mesoscale circulations ...

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

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 777, April 2026 Part B.
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.

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 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 ...

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.

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 ...
