| Where: | Maxwell Dworkin G125 |
This talk will present a collection of numerical methods, which are
combined into a single framework for aerodynamic and fluid-structure
interaction (FSI) modeling and simulation of wind turbines. The
numerical formulation of the Navier-Stokes equations of incompressible
flows is validated using experimental data for a full-scale wind
turbine. The structural modeling of wind turbine blades makes use of the
Kirchhoff—Love thin shell theory discretized with isogeometric analysis
(IGA) based on non-uniform rational B-splines (NURBS). The coupled FSI
formulation accommodates non-matching fluid-structure interface
discretizations. The challenges of fluid-structural coupling and the
handling of the computational mesh in the presence of large rotational
motions will be discussed, and the FSI computations of a 5MW offshore
baseline wind turbine rotor are shown. Extensions of the current
modeling and simulation methodology to the case of free surface flow and
FSI, which are used for modeling of offshore wind turbines, will also
be discussed if time permits.

| Speaker Biography: | Yuri Bazilevs is an Assistant Professor of Structural Engineering at UC San Diego . He received his Ph.D. in 2006 from the Institute for Computational Engineering and Sciences (ICES) at the University of Texas at Austin. Yuri works on computational methods for fluid-structure interaction (FSI), biomechanics, and turbulent flow. He is one of the original developers of isogeometric analysis and is co-author with J. A. Cottrell and T. J. R. Hughes of the book "Isogeometric Analysis: Toward Integration of CAD and FEA". |
