Available in PDF, EPUB and Kindle. Book excerpt: The state-of-the-practice methods for aerodynamic design of wind turbine blads use linearized blade element momentum theory (BEM) to optimize the twist and chord profiles from a pre-selected set of 2D airfoil shapes. In this work, we apply invertible neural network (INN) tools to enable the rapid inverse aerodynamic design of wind turbine blades including component airfoils. The INN is trained on data obtained through the use of robust automated mesh generation and the HAMSTR computational fluid dynamics solver with advanced turbulence and transition models validated for turbine applications. Our design technique is a significant improvement over the state-of-the-practice linearized blade element momentum (BEM) techniques in capturing 3D nonlinear aerodynamic effects that are critical for optimal design of the rotors. This is made possible by developing sparse, invertible neural networks (INNs) for inverse design and optimization that realize a 100x cost reduction compared to adjoint-based computational fluid dynamics (CFD) approaches, while enabling increased robustness of the final design. We demonstrate the INN tool for design of a section of the NREL 5-MW blade. All generated shapes satisfy the desired aerodynamic characteristics, demonstrating the success of the INN approach for inverse design of wind turbine blades.

This book was released on 2012 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inverse design of centrifugal pump impeller blades is a widely used technique for designing pump blades. In a typical Computational Fluid Dynamics (CFD) analysis, the geometry (flow domain) is prescribed, and the governing equations are solved over the flow domain, subject to appropriate boundary conditions. In the inverse design technique, the geometry is unknown, while the desired flow field characteristics on the geometry (blades of pump impeller) are prescribed. Starting with an initial guess for the blade shape, the final shape of the blades is obtained iteratively. The present work uses OpenFOAM, an open source CFD software, which solves the governing equations using a finite-volume method (FVM) for the inverse design of two-dimensional centrifugal pump impeller blades. A CFD analysis using FVM requires mesh to be of good quality. Since the pump blade has high curvature, careful consideration has to be given while generating the mesh. The present work explains the geometry generation and meshing of the geometry, to obtain a good quality mesh in the Gambit software. The inverse design technique in the present study is based on assumption of a potential flow field. In the potential flow analysis of pumps, the circulation generated by a pump is an unknown. This unknown appears in a boundary condition downstream of the blade. An iterative method has been implemented in OpenFOAM for calculating the circulation. The circulation value calculated using OpenFOAM compares well with analytical value of circulation generated for the test case of an impeller with logarithmic spiral blades. A grid-independence study shows that, as the grid is refined, the value of the circulation generated by the pump impeller approaches the analytical value. Inverse design is an iterative process, which is carried out till a converged blade shape is obtained, while satisfying the prescribed flow characteristics. For every new shape generated during iteration, the geometry creation and grid generation are automated using a Journal file in Gambit. The mesh is then imported in OpenFOAM. Inverse design of a pump blade requires specification of swirl distribution along the blade. To accommodate this swirl distribution in the boundary condition on the blade, the OpenFOAM code is modified. The iterative process has been automated, and linked with Gambit, using a Linux shell script. The implementation of the present inverse design process in OpenFOAM is verified for a two-dimensional case. The swirl distribution generated on the blade is calculated by analyzing potential flow in a blade-to-blade channel for an assumed blade shape. This swirl distribution is then imposed on a flat blade, and the inverse design iterations are carried out, till a converged blade shape is obtained. This inverse design blade shape matches closely with the assumed shape of the blade. The method is further used to redesign a blade which has non-zero incident flow at the leading edge. The inverse design method redesigns the blade such that the flow is tangential to the blade at leading edge. Following chapters explain the implementation of inverse design method using Gambit and OpenFOAM.
