Support Structure Modelling in Actuator Line Method Large Eddy Simulations of Wind Turbine Wakes

open access: yesWind Energy, Volume 29, Issue 1, January 2026.
ABSTRACT While advancements in the prediction of wind turbine loads and wakes within the actuator line method large eddy simulation (ALM‐LES) framework have been an active research topic in recent years, the modelling of the tower and nacelle has received comparatively less attention.

Effect of Grouting Pressure and Nozzle Diameter on the Diffusion Mechanism of Jet Grouting: A CFD–DEM Study

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Grouting diffusion range is the key to evaluate the grouting effect. In this study, a theoretical model of noncohesive sediment erosion damage was established, and the main parameters affecting erosion were qualitatively analyzed. Secondly, based on the computational fluid dynamics (CFD)–discrete element method (DEM) coupling method, the effect of ...

A Lucas Operational Matrix Method for Solving Nonlinear Fractional Two‐Dimensional Partial Volterra Integral Equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
This paper introduces a new numerical method for solving a class of two‐dimensional fractional partial Volterra integral equations (2DFPVIEs). Our approach uses Lucas polynomials (LPs) to construct operational matrices (OMs) that effectively transform the complex fractional‐order equations into a more manageable system of algebraic equations.

Incremental Model Order Reduction of Smoothed‐Particle Hydrodynamic Simulations

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 97, Issue 12, Page 1571-1594, December 2025.
The paper presents the development of an incremental singular value decomposition strategy for compressing time‐dependent particle simulation results, addressing gaps in the data matrices caused by temporally inactive particles. The approach reduces memory requirements by about 90%, increases the computational effort by about 10%, and preserves the ...

Comparison of the Particle Finite Element Method (PFEM) and Finite Element Method (FEM) on a Linear Elastic Heterogeneous Test Specimen

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 25, Issue 4, December 2025.
ABSTRACT In industrial manufacturing, large share of machining tools are produced using materials such as tungsten carbide, due to their exceptional properties. However, they are now classified as critical, due to the limited availability of constituents and the accompanying social‐environmental concerns related to their mining and processing.
