A Feasibility Study of a Tension-Leg Platform for Hydro-Powered Turbines System and Metocean Data Analysis for Floating Wind Turbine Design
Marine and wind energy stand as promising frontiers for clean and sustainable power generation. The first chapter of this study explores the feasibility of implementing a Tension Leg Platform (TLP) for a hydropower turbine system with an overall rated power of 1500 kW. The TLP semi-submersible …

Design and testing of a concentrator wind turbine
Wind energy, being an indirect form of solar energy would initially seem a very promising form of energy. Unfortunately, it suffers from the problem of dilution. Wind turbine designers naturally try to compensate for this by increasing the size of the rotor to capture more of the kinetic energy of …

Multidisciplinary design optimization of dynamic systems using surrogate modeling approach
… for efficient solution of multi-disciplinary design optimization (MDO) of dynamic systems. Many of the MDO problems in dynamic systems design often involve computationally expensive system simulations, severely limiting their design optimization. This work demonstrates a novel method which …

The Influence of Yaw and Coning on Small Bio-Inspired Wind Turbines
… mechanism of samaras. The study consists of wind tunnel measurements of low aspect ratio horizontal-axis wind turbine models. The tested coning angles (β) ranged from 5◦ to 25◦, and power and tip-speed ratio were measured at Reynolds numbers Re_D = [0.46 ×10^5, 1.8 ×10^5]. Results show that …

An integrated CAD methodology applied to wind turbine optimization
Modern engineering practice for designing physical products requires the creation of a CAD model of the design for documentation and manufacturing. As the design evolves from concept through to production, it is analyzed a number of times, in some cases using general parameters and in others …

Influence of geometry on the dynamic behaviour of steel tubular towers for onshore wind turbines
… trend to become more environmentally friendly. Wind power, specifically, is to account for a large portion of the renewable energy that is expected to become available by 2030. This results in the need for the understanding of wind turbine design by South African engineers. The dynamic analysis …

Turbulence Modeling and Simulation of Unsteady Transitional Boundary Layers and Wakes with Application to Wind Turbine Aerodynamics
Wind energy industry thrived in the last three decades, environmental concerns and government regulations stimulate studies on wind farm location selection and wind turbine design. Full-scale experiments and high-fidelity simulations are restrictive due to the prohibitively high cost, while the …

Unsteady separation control on wind turbine blades
… one of the primary causes of unsteady loads on wind turbine blades. The process can be instigated by a multitude of factors, common in wind turbine operating environments, such as inflow turbulence, wind gusts and sustained yaw misalignment. The unsteady separation due to dynamic stall can lead …
