This study sheds light on the post-equilibrium sea bed scour mechanism around a wind turbine. The simulation results explain the influence of different hydrodynamic mechanisms on the local scours in a cohesive fluid, such as periodic waves, random waves, and constant currents. The conventional Bingham model is adopted as the fundamental model. However, due to the intrinsic characteristic, the Bingham model cannot illustrate the stratified material satisfactorily.

Long fibre reinforced polymer composite materials have found many applications in many industries, such as aerospace, automotive, marine, wind turbine, and sports. Techniques for the manufacturing of structures used in these industries have been mainly Hand Lay Up (HLU), and Liquid Composite Moulding. While there are a few automated methods of manufacturing, such as Filament Winding and Pultrusion, these techniques are restricted to make structures that consist of surfaces of revolution, or fibres that are aligned only along one direction.

Another significant driver—in a world now more environmentall conscious than ever—is a global thrust to develop projects whic not only minimize GHG emissions but also help to displace GHG emissions from other industrial sources. Thus, one of the more significant advantages of gas-turbine and engine-based cogeneration is the potential for significant GHG reductions. Further, it is the monetization of GHG reductions and other poss financial incentives that are helping to encourage and facilitate development of cogeneration applications.

In 1993, the U.S. Department of Energy (DOE) Office of Industrial Technology (OIT) established a group of seven industries designated as Industries of the Future (IOF). These industries were selected for their high energy use and large waste generation. The original IOF included the aluminum, chemicals, forest products, glass, metalcasting, petroleum refining, and steel industries. Each industry was asked to provide a future vision and a road map detailing the research required to realize its vision.

Materials are evolving today faster than at any time in history. Industrial nations regard the development of new and improved materials as an “underpinning technology” – one which can stimulate innovation in all branches of engineering, making possible new designs for structures, appliances, engines, electrical and electronic devices, processing and energy conservation equipment, and much more.

Innovation in engineering often means the clever use of a new material - new to a particular application, but not necessarily (although sometimes) new in the sense of ‘recently developed’. Plastic paper clips and ceramic turbine-blades both represent attempts to do better with polymers and ceramics what had previously been done well with metals. And engineering disasters are frequently caused by the misuse of materials.

Wind power generation is considered as the most economic viable alternative within the portfolio of renewable energy resources. Among their advantages are the large number of potential sites for erection and the rapidly evolving technology with many suppliers offering from the individual turbine set to even turnkey projects. The disadvantages of wind energy include high capital costs and lack of controllability on the discontinuous or intermittent resource.

The term magnetic bearing refers to devices that provide stable suspension of a rotor. Because of the contact-less motion of the rotor, magnetic bearings offer many advantages for various applications. Commercial applications include compressors, centrifuges, high-speed turbines, energy-storage flywheels, high-precision machine tools, etc. Magnetic bearings are a typical mechatronic product. Thus, a great deal of knowledge is necessary for its design, construction and operation.

Humanity is facing several critical global challenges at the beginning of the 21st century. One of which includes the quest for alternative energy resources that mitigate the dependence on fossil fuels. Whereas fossil fuels are available in situ at all times, the utilisation of renewal energies has to cope with large temporal fl uctuations ranging from seconds to seasons.
