Abstract

This paper describes aerodynamic characteristics for the NREL(National Renewable Energy Laboratory) Phase VI rotor using the Fluent which is a commercial flow analysis tool. Aerodynamic analysis results are compared with experimental results by the NREL/NASA Ames wind tunnel tests. For three velocity cases, computed results are compared with experiment results at five spanwise positions. Computed results represented good agreement with the experimental results at low velocity. Otherwise computed results in suction side represents disagreement with the experimental results at high velocity. When interval between wind turbines is 10 times of rotor diameter, CFD research is performed to calculate the wake effect.

본 논문은 상용유동해석코드인 Fluent를 이용하여 NREL(National Renewable Energy Laboratory) Phase VI 로터에 대한 공력특성을 연구하였다. 해석 결과는 NREL/NASA Ames 풍동 시험결과와 비교하였다. 풍력터빈로터의 반경방향에 대해 속도의 변화에 따른 압력분포를 비교하였다. 계산된 결과는 저속일 때 실험결과와 잘 일치 하였지만 고속일 때 블레이드의 suction side에서 실험결과와 잘 일치하지 않았다. 2기의 풍력터빈간의 거리가 풍력터빈 로터지름의 10배일 때 후류의 영향을 고려한 후방 풍력터빈 로터의 공력해석을 수행하였다.
