Flow curvature effects on dynamic behaviour of a novel vertical axis tidal current turbine: numerical and experimental analysis [PDF]

, 2005
The paper deals with performances analysis of vertical axis turbine to exploit tidal marine currents. Flow curvature effects on performences of a novel vertical axis turbine have been investuigated. It has been shown that the flow curvature effect allows

Insights Into the Mechanisms Controlling the Residual Strength of Bio‐cemented Sands

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Microbially induced carbonate precipitation (MICP) is an emerging technique for enhancing the mechanical properties of granular soils. Although several experimental studies have reported increased shear strength in MICP‐treated soils at both peak and residual states, other findings have shown reductions in residual strength compared to ...

Combined Structural Optimization and Aeroelastic Analysis of a Vertical Axis Wind Turbine [PDF]

, 2015
Floating offshore wind energy poses challenges on the turbine design. A possible solution is vertical axis wind turbines, which are possibly easier to scale-up and require less components (lower maintenance) and a smaller floating structure than ...

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

Polymer Composites, EarlyView.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

Review on Floating Foundation Structures for Offshore Wind Turbines

Zhongguo dianli, 2020
With the gradual increase of renewable and clean energy demand in China, the development of onshore wind energy tends to be saturated. It is an inevitable trend for wind power to be applied in offshore and deep-sea areas.

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed
