On the limiting parameters of artificial cavitation applied to reduce drag [PDF]
, 2003 Artificial cavitation, or ventilation, is produced by releasing gas into liquid flow. One objective of creating such a multiphase flow is to reduce frictional and sometimes wave resistance of a marine vehicle completely or partially immersed in the ...

Polymer Composites, Volume 46, Issue S1, Page S9-S25, 10 September 2025.Typical manufacturing defects and mitigation strategies in thick thermosetting composites. Abstract The composite part industry is currently dominated by thin‐section geometries. However, thick composites gain interest in many applications where monolithic parts are required, such as foils, wind mill root blades, and so forth.

Flow and air-entrainment around partially submerged vertical cylinders [PDF]
, 2019 In this study, a partially submerged vertical cylinder is moved at constant velocity through water, which is initially at rest. During the motion, the wake behind the cylinder induces free-surface deformation. Eleven cylinders, with diameters from $D=1.4$

Wind Turbine Optimization by Blade Element Momentum Method and Particle Swarm Optimization Technique
Journal of Engineering, Volume 2025, Issue 1, 2025.The aerodynamic efficiency of wind turbines is greatly influenced by the shape of their airfoils. In this study, four airfoils were optimized to enhance the performance of a small horizontal axis wind turbine. The optimization process involved adjusting the thickness and camber of the airfoils using the blade element momentum method and particle swarm ...

Energy Science &Engineering, Volume 12, Issue 12, Page 5555-5565, December 2024.Turbine attached to the train structure of the water‐circulating tunnel. ABSTRACT Hydrokinetic turbines (HTs) extract power by utilizing hydrodynamic forces from flow energy. The surplus load not used for power generation acts as a system load and must be considered when designing the turbine.

Control of a flexible, surface-piercing hydrofoil for high-speed, small-scale applications [PDF]
2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2017 In recent years, hydrofoils have become ubiquitous and critical components of high-performance surface vehicles. Twenty-meter-long hydrofoil sailing craft are capable of reaching speeds in excess of 45 knots. Hydrofoil dinghies routinely travel faster than the wind and reach speeds up to 30 knots.
