DELFT UNIVERSITY OF TECHNOLOGY Department of Precision and Microsystems Engineering 13 August 2017 To: the staff of PME the students of PME Subject: PME-Final Presentation MSc Project We are pleased to invite you to attend the PME- Final Presentation MSc Project at: Tuesday 20 August 2013 Lecture-room James Watt (D) Mekelweg 2 2628 CD DELFT 12.45 hrs S.F. van den Broek, specialisation: Engineering Mechanics Title: Framework for Aeroelastic Wind Turbine Blade Analysis The trend in the last few years has been to increase the amount of wind energy in our energy mix. The design of wind turbine blades involves modeling structures, aerodynamics as well as control systems and coupling together in an aero-servoelastic code. Modern wind turbines are designed using relatively low fidelity simulation models based on beam or modal models of the structure. These models are usually limited in their ability to model effects such as bend-twist coupling which are important for the modeling of aeroelastic tailoring. The design of wind turbine blades combines aerobatic modeling with Modern aerospace optimization and analysis use more advanced structural and aerodynamic solvers. As part of a new effort at the University of Michigan a new, higher-fidelity aerostructural code has been developed. This code uses a widely used blade element momentum (BEM) code (AeroDyn) and couples it to an in-house structural solver which is particularly suited for optimization studies. The coupled code is converged to a steady-state (static) solution. The coupled code is compared to an existing lower fidelity code using a model based on the NREL 5 MW wind turbine. This code will be used in future projects to do time-domain analysis and optimization. The presentation will be given in English. 13.10 hrs Debate 13.30 hrs End Attending colloquia is an obligatory part of the curriculum of PME. The presence of other people who are interested will be appreciated.
