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.

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
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
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
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 ...

Abstract Accurate prediction of air‐sea fluxes hinges on a deep understanding of wind‐wave interactions, yet feedback mechanisms involving surface waves and wind are not fully understood. This paper investigates the effect of two‐way coupling between wind and waves on wind turbulence through direct numerical simulation of air‐water two‐phase flows ...
