A Stable Hybridized Discontinuous Galerkin Method for Solving Some Nonlinear m‐Component Reaction–Diffusion Systems

Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 12405-12420, August 2025.
ABSTRACT In this paper, we present a stable numerical scheme for solving two‐dimensional m$$ m $$‐component reaction–diffusion systems. The proposed approach utilizes the backward Euler method for temporal discretization and the hybridized discontinuous Galerkin (HDG) method for spatial discretization.

Enhanced Aerodynamic Performance of Savonius Wind Turbines Through Blade Design Modifications: A CFD Study

Wind Energy, Volume 28, Issue 8, August 2025.
ABSTRACT The conventional Savonius wind turbine's power coefficient is comparatively low, which limits its efficiency. Because the power coefficient depends significantly on the blade design, this study investigates the potential of improving the turbine performance by modifying the rotor blade designs.

Meteorological Assessment of Vertical Axis Wind Turbine Energy Microgeneration Potentials Across Two Swiss Cities Located in Complex Terrain

Wind Energy, Volume 28, Issue 8, August 2025.
ABSTRACT Wind energy is the most mature renewable energy technology; however, its exploitation in cities is often met with skepticism. Thanks to their ability to operate at low wind speed regardless of direction, vertical axis wind turbines (VAWTs) offer an attractive opportunity for wind energy harvesting in cities. However, limited evidence exists on

Spline‐Based Framework for Microscopic Contact Zone Modeling in Lubricated Orthogonal Cutting

International Journal for Numerical Methods in Engineering, Volume 126, Issue 14, 30 July 2025.
ABSTRACT Accurately predicting the coefficient of friction between tool, chip, and workpiece during machining is essential for a reliable and cost‐effective process. In this context, current numerical methods are often based on homogenized approaches with friction models that use constant friction coefficients; thus, failing to capture local effects ...

Turbulence of Tropical Cyclones: From Peristrophic to Zonostrophic

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 14, 28 July 2025.
Abstract Cyclostrophic rotation in the core region of tropical cyclones (TCs) imprints a distinct signature upon their turbulence structure. Its intensity is characterized by the radius of maximum wind, Rmw ${R}_{mw}$, and the azimuthal wind velocity at that radius, Umax ${U}_{max}$.

Climate‐Driven Stratification Intensifies Internal Wave Cooling on a Shallow Island Reef

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract As ocean temperatures rise, understanding the cooling role of internal waves is crucial for reef preservation. Climate‐induced surface warming increases stratification, altering internal wave propagation. We use high‐resolution, nonhydrostatic simulations at Dongsha Atoll in the South China Sea to explore seasonal bottom temperature changes ...

Integrating the Probe and Singular Sources Methods: II. the Stokes System

Mathematical Methods in the Applied Sciences, Volume 48, Issue 10, Page 10406-10426, 15 July 2025.
ABSTRACT In this paper, an integrated theory of the probe and singular sources methods for an inverse obstacle problem governed by the Stokes system in a bounded domain is developed. The main results consist of the probe method for the Stokes system, the singular sources method by using the notion of the probe method, and the completely integrated ...

The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples

Advanced Theory and Simulations, Volume 8, Issue 7, July 2025.
FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,
