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 ...

LES-based investigation on external heat transfer characteristics of turbine blades for gas turbine (About the effect of turbine blades configuration)

Nihon Kikai Gakkai ronbunshu, 2015
Accurate prediction of external heat transfer around a turbine is important in high efficiency gas turbine development. Experimental and computational fluid dynamics studies were performed to investigate the heat transfer characteristics around two types

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 ...

Intercomparison of CFD Simulations for Urban Flow in Paris: OpenFOAM, code_saturne, and the PALM Model System

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
ABSTRACT This study quantifies uncertainty in CFD‐based urban flow simulations over central Paris using three modeling approaches: steady RANS with OpenFOAM, unsteady RANS with code_saturne, and LES with PALM. All simulations are validated against field measurements and show overall good agreement.

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 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 ...
