Application of a Local Dynamic Model of Large Eddy Simulation to a Marine Propeller Wake

Applied Sciences, 2023
With recent development of computer technology, the use of large eddy simulation method to solve industrial problems is gaining acceptance. From a theoretical and applied perspective, a local dynamic k-equation subgrid-scale model is applied to study the

Vibrational Exfoliation of 2D Materials

Small, EarlyView.
Vibrational energy folds, fractures and exfoliates atomically and molecularly thin materials. Combining experimentation and computational methods, this unique vibrational synthesis pathway is revealed. This process overcomes barriers of existing approaches by processing 1000 g/L dispersions without loss in yield.

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

steel research international, EarlyView.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

The Ceiling Height of Wildland Fire Plumes in Quasi‐Steady Stratified and Sheared Boundary Layers

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Radar observations from a prescribed fire experiment reveal a large‐scale, billow‐like vorticity structure associated with the plume head near the onset of plume bending. This bending limits the vertical extent of the plume and defines the characteristic plume ceiling height.

Introducing the Coincidence Index: A Novel Diagnostic and Production‐Based Framework for Water Body Interaction Analysis and Its Application to Study the Interaction of River Plumes

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Quantifying interactions between distinct water bodies is critical yet challenging for understanding ocean and estuarine dynamics. We introduce the coincidence index (CI), defined as the product of two arbitrary tracers (a $a$, b $b$), to diagnose where two water masses coexist and mix.

Calibration of a Neural Network Ocean Closure for Improved Mean State and Variability

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Global ocean models exhibit biases in the mean state and variability, particularly at coarse resolution, where mesoscale eddies are unresolved. To address these biases, parameterization coefficients are typically tuned ad hoc. Here, we formulate parameter tuning as a calibration problem using Ensemble Kalman Inversion (EKI).

Landfall Reorganizes Eyewall Boundary Layer Transport and Scale Coupling in Typhoon Hato (2017)

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Landfall reorganizes the tropical cyclone eyewall boundary layer (BL) through elevated surface roughness and reduced enthalpy fluxes. Using a 100‐m resolution nested large‐eddy simulation of Typhoon Hato (2017), we compare eyewall BL structures before and during landfall.

Examining OpenFOAM-based LES analysis in terms of inviscid energy conservation and viscous turbulence decay

Mechanical Engineering Journal
The present study examines an OpenFOAM-based LES analysis from the viewpoints of inviscid energy conservation and viscous turbulence decay. The Smagorinsky model is employed as the sub-grid scale (SGS) model, and a two-dimensional periodic analytical ...

Scale‐up of Streptomyces species cultivations based on the morphological response to the energy dissipation rate

AIChE Journal, Volume 72, Issue 7, July 2026.
Abstract Filamentous microorganisms exhibit complex morphologies that influence product formation and are affected by various bioprocess parameters. Consistent morphology is therefore essential for comparable results during scale‐up. This study investigates the scale‐up of Streptomyces species (Streptomyces spp.) cultivations from shake flasks to ...
