本论文介绍了作者在风力机空气动力学领域的研究工作，特别是风力机应用的被动和主动流动控制解决方案。基本理论描述是伴随着一个彻底的文献综述，其中许多不同的流量控制解决方案进行了简要分析。在分析过程中，除了空气动力学性能外，还特别努力包括广泛的技术领域，从而试图提供全面的研究。然后，通过流动模拟（CFD）、风洞试验以及气动弹性模拟，对性能最佳的解决方案进行了全面分析。通过这种分析，可以估计这种解决方案在风力涡轮机应用中的优点。最后一章介绍了一种配备流量控制解决方案的虚拟风力涡轮机“智能”旋翼。作者的目的是，这项工作将能够作为进一步研究其他流量控制解决方案的基础。以及新的流量控制概念的发展，这将克服目前的缺点。
The current thesis describes the research work of the author in the field of wind turbine aerodynamics and especially passive and active flow control solutions for wind turbine applications. The basic theory description is accompanied by a thorough literature review where many different flow control solutions are briefly analyzed. Special efforts have been made to include a wide range of technical fields, apart from aerodynamic performance, in the analysis process and thus try to provide a comprehensive study. The best performing solutions are then thoroughly analyzed by means of flow simulations (CFD), wind tunnel tests as well as aeroelastic simulations. Through this analysis it is possible to estimate the merits of such solutions for wind turbine applications. A final chapter with a fictive wind turbine "smart" rotorbade, equipped with flow control solutions is finally presented and discussed in this thesis. The aim of the author is that this work will be able to function as a base for further research of other flow control solutions...as well as for the development of new flow control concepts, which will overcome current drawbacks.
