Performance analysis and characterization of a new wind turbine ice protection system

该项目将分析由加拿大Borealis Wind公司开发的新型热空气防冰系统的性能和特性。为了提高效率，Borealis提出的冰保护系统必须依靠两个主要方面。第一个方面处理风力涡轮机的特点，其中系统将被安装。叶片的几何形状、旋转速度、加热功率和空气在叶片中循环的方式影响着系统限制的性能，每一种都以自己的方式影响着总体传热能力和叶片的外部温度。要处理的第二个方面是涡轮机运行时的气象条件。为了取得成功，冰保护系统的性能必须与涡轮机的运行条件相匹配。这次合作的长期目标是改进Borealis风冰保护系统的建模，并评估这种改造系统将有效的条件。

This project will analyze the performances and characterize the behaviour of a new hot air ice protection system develop by Canadian company Borealis Wind. To be efficient, ice protection systems such as the one proposed by Borealis must rely on two major aspects. The first aspect deals with the features of the wind turbine where the system is to be installed. The geometry of the blades, the rate of rotation, the heating power and the way the air is circulated in the blade affects the performance of the system limiting, each in in their own way, the overall heat transfer capacity and the outside temperature of the blade. The second aspect to be dealt with is the meteorological conditions under which the turbine is operated. In order to be successful, the performance of the ice protection system must match the conditions under which the turbine is operated. The long term objective of this collaboration is to improve the modeling of Borealis Wind ice protection system and to assess the conditions under which such retrofit system would be efficient.
