Hydro‐Climatic Modelling for Water Resources: From Processes to Adaptive Management and Governance

Hydrological Processes, Volume 39, Issue 12, December 2025.
This study explores hydro‐climatic modelling through theoretical analysis, experimental investigations and advanced simulations (DNS, LES, CFD). By examining multi‐scale dynamics, microphysical processes and biogeochemical cycles (water, carbon, nitrogen), it analyses feedback complexities and cross‐scale interactions.

Development of a Novel Rotor Design for Counter‐Current Centrifugal Extraction Based on Computational Fluid Dynamics Simulations

Journal of Separation Science, Volume 48, Issue 12, December 2025.
ABSTRACT This study introduces an innovative method for continuous multistage liquid–liquid extraction. Addressing challenges like coalescence and settling times that limit efficiency makes centrifugal partition extraction a promising technique for continuous product separation.

Data‐Driven Detection of Internal Erosion Initiation in Gap‐Graded Soils: Combining Particle‐Scale CFD‐DEM Simulation With 3D Convolutional Autoencoder

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 17, Page 4225-4247, 10 December 2025.
ABSTRACT Internal erosion in gap‐graded soils poses significant risks to water‐retaining structures such as earth dams. However, its underlying mechanisms at the particle scale remain poorly understood. This study couples the discrete element method (DEM) with computational fluid dynamics (CFD) to simulate internal erosion in gap‐graded soil assemblies

Towards an Improved Wall Function Formulation for Reynolds‐Averaged Navier–Stokes Simulations of Turbulent Concentric Coaxial Pipe Flows

PAMM, Volume 25, Issue 4, December 2025.
ABSTRACT Concentric coaxial (annular) pipe flow is numerically investigated using a high Reynolds number (HRN) Reynolds‐Averaged Navier–Stokes (RANS) approach, given direct numerical simulation (DNS) boundary conditions. Previous work has shown that traditional wall models fail in predicting bulk quantities due to insufficient representation of the ...

Determination of Crystallization Kinetics of Polyetheretherketone in Material Extrusion Process Using Numerical Simulation

Polymers for Advanced Technologies, Volume 36, Issue 12, December 2025.
ABSTRACT Despite considerable progress over the past 3 years, some issues remain in obtaining printed polyetheretherketone (PEEK) parts printed by the material extrusion process (MEX). The fast crystallization of PEEK during printing results in distortion, poor dimensional accuracy, and low inter‐filament adhesion.

Modeling angiogenesis under Robin boundary conditions

Quantitative Biology, Volume 13, Issue 4, December 2025.
Abstract In this study, we show an example of a numerical model based on the Keller–Segel system of equations to simulate angiogenesis in response to chemotaxis under Robin boundary conditions, which represent the presence of flux at the tumor. Different parameters of the model are modified to identify key biological factors relevant to the behavior of
