Effect of interaction between blade and tower in upwind type HAWT on blade aerodynamic performance and load
Upwind형 수평축 풍력발전기의 타워 영향에 의한 블레이드 공력 성능 및 하중 변화에 대한 고찰
Abstract
This paper describes the effects to wind turbine blade aerodynamics due to interaction between blade and tower on upwind type HAWT. In order to analyze effects of blade-tower interact ion, the analyst s program WINFAS which is based on VLM(Vortex Lattice Method), Free wake and FVE model is used. In this study, the changes of wind turbine blade aerodynamics caused by blade-tower interact ion are Investigated with various parameters windshear, yaw error, TSR and tower diameter.
