Parametric Design of Turbomachinery Blades
EUROCON 2005 - The International Conference on "Computer as a Tool", 2005A software is presented for the design of turbomachinery blades. It provides the ability to interactively construct 3D turbomachinery parametric bladings of various types. The blades' as well as the hub and shroud surfaces are modeled as NURBS 3D surfaces, although the design parameters used for their construction correspond to 2D sections.

Flow deflection in turbomachines is established by stator and rotor blades with prescribed geometry that includes inlet and exit camber angles, stagger angle, camber line, and thickness distribution. The blade geometry is adjusted to the stage velocity diagram which is designed for specific turbine or compressor flow applications.

Design of Swept Blade for Turbomachinery
Volume 3: 25th Computers and Information in Engineering Conference, Parts A and B, 2005To meet the needs of efficient turbine blade designs, CFD predictions of a complex 3D flow field in turbine blade passages have been incorporated in the design process during the last decade. Owing to the numerous advantages possessed by a 3-D CFD technology many industries already use a 3D blading technique in the design process of turbomachines.

Computational Design of Turbomachine Blades
Journal of Aircraft, 1980Based upon Wu's general three-dimensional turbomachine flow theory, a set of computer programs was established to measure flow along the relative stream surfaces S1 and S2, employing nonorthogonal curvilinear coordinates and nonorthogonal velocity components.

Impact of Aerodynamics on Blade Design
2014Now having introduced all knowledge from fluid mechanics, it is high time to try to give an overview on what is really used in practical wind turbine blade design. Referring to Chap. 10 and esp. Figure 10.1, we see that with the development of huge offshore wind turbines up to 170 m rotor diameter, a period of exponential growth has started again after

Modeling of uncertainties for wind turbine blade design
2014Wind turbine blades are designed by a combination of tests and numerical calculations using finite element models of the blade. The blades are typically composite structures with laminates of glass-fiber and/or carbon-fibers glued together by a matrix material.

An Evolutionary Environment for Wind Turbine Blade Design
2005The aerodynamic design of wind turbine blades is carried out by means of evolutionary techniques within an automatic design environment based on evolution. A simple, fast, and robust aerodynamic simulator is embedded in the design environment to predict the performance of any turbine produced as intermediate individual of the evolutionary process.

Integration of Airfoil Design During the Design of New Blades
2013Despite the fact that the design of a new blade is a multidisciplinary task, often the different disciplines are combined together at later stage. Looking at the aerodynamic design, it is common practice design/select the airfoils first and then design the blade in terms of chord and twist based on the initial selection of the airfoils.

Integrated aerodynamic design and analysis of turbine blades
Advances in Engineering Software, 2014This paper presents an integrated approach for aerodynamic blade design in an MDO (multidisciplinary design optimization) environment. First, requisite software packages and data sources for flow computations and airfoil modeling are integrated into a single cybernetic environment, which significantly enhances their interoperability.
