The drive for the cost reduction of floating offshore wind turbine (FOWT) systems to the levels of fixed bottom foundation turbine systems can be achieved with creative design and analysis techniques of the platform with free-form curves to save numerical simulation time and minimize the mass of steel (cost of steel) required for design. This...

Nowadays, low-duty CNC machines use the conventional belt-driven system, which works well for relatively small machines. However this design brings several complications the engineer has to account for: creep; backlash; complex assembly and more importantly the limited stiffness of the belt. This limited stiffness results in belt stretch and...

The goal of this study is to understand the processes and wing characteristics that influence lift generation of a flapping wing, and apply the acquired knowledge in an optimization setting to obtain an optimal wing thickness distribution which maximizes effective wing lift. To achieve this, an extensive literature survey was conducted to...

Topology optimization is a strong approach for generating optimal designs which cannot be obtained using conventional optimization methods. Improving structural characteristics by changing the internal topology of a design domain has been fascinating scientists and engineers for years. Topology optimization can be described as a distribution of...

The traditional Dutch way to deal with piping failure in river dikes is the implementation of piping berms. The disadvantage of such a measure is the required inland space. Relief wells, on the other hand, require less or no inland space representing an attractive alternative solution. The aims of this paper are first, to show how reliability...

A large number of wind energy installations exist on rich wind resource sites. Nevertheless, estimates show that about 50% of the world’s wind energy resource has a wind speed of 7 m/s or less. For these low wind speed resource areas, low wind turbine technology is required. For this reason, this DTU Wind Energy master project, in cooperation...

This thesis introduces a new parameterization technique based on the Class-Shape-Transformation (CST) method. The new technique consists of an extension to the CST method in the form of a refinement function based on B-splines. This Class-Shape-Refinement-Transformation (CSRT) method has the same advantages as the original CST method, while also...

Traditionally, the aircraft design process is divided into three phases: conceptual, preliminary and detailed design. In each subsequent phase, the fidelity of the analysis tools increases and more and more details of the design geometry are frozen. In each phase a number of design variants is generated, fully analyzing them with the tools...
