NACA翼型が二重反転プロペラ風車の性能に及ぼす影響

抄録

Small wind power generation is expected as the development of new energy sources accelerates. Therefore, this study focuses on contra-rotating propeller wind turbines, which are suitable for operation under internal flow conditions, and aims to increase the output of small wind turbines. Specifically, we investigate the performance characteristics of the contra-rotating propeller wind turbine by numerical flow analysis using a model with the contra-rotating propeller installed inside the pipe. In this paper, we focus on the NACA airfoil, and show the results of investigating their performance characteristics and internal flow by numerical analysis.
