Primary objective in wind turbine design is to maximize the aerodynamic efficiency, or power extracted from the wind. But this objective should be met by well satisfying mechanical strength criteria and economical aspects. In this video we will see impact of number of blades, blade shape, blade length and tower height on wind turbine design. The next big factor which is affecting performance of wind turbine is shape and orientation of blade cross section. A moving machine experiences fluid flow at a different velocity than the actual velocity. It is called as relative or apparent velocity. Apparent velocity of flow is difference between actual flow and blade velocity. Absolute velocity of the flow is shown in first figure, while apparent velocity in the second figure. It is clear that apparent velocity of flow is vectorial difference between actual and blade velocity. The vector difference is shown in the first figure at a particular cross section. A rotating blade will experience an apparent velocity of flow.

The heterogeneity in a composite material is introduced due to not only its bi-phase or in some cases multi-phase composition, but also laminations. This leads to a distinctly different stress strain behaviour in the case of laminates. The anisotropy caused due to fibre orientations and the resulting extension-shear and bending-twisting coupling as well as the extension-bending coupling developed due to unsymmetric lamination add to the complexities. A clear understanding of the constitutive equations of a composite laminate is thus desirable before these are used in analysis and design of composite structures. In this chapter, we first introduce to the readers the basic constitutive equations for a general three-dimensional anisotropic material with and without material symmetry, elastic constants and compliances and their relations to engineering constants, as well as transformation laws for elastic constants and compliances for both three and two-dimensional cases.

Last month, D-Sight Web was updated with a pretty awaited feature: spitting the work between experts when evaluating alternatives and defining preferences in a decision process. In other words and without going into too much details (for that, read the release announcement), this typically allows for a technical expert to only provide input for technical criteria and for a legal expert to focus on legal criteria – for instance.
