Abstract

It is essential to consider the effect of blade deformation in order to design a better tidal stream turbine being operated in off-design condition. Flow load causes deformation on the blade, and the deformation affects the turbine performance. In the present study, CFD analysis procedures were developed to predict open water performance of horizontal axis tidal stream turbine (HATST). The developed procedures were verified by comparing the results with existing experimental results. Fluid-structure interaction (FSI) analysis method, based on the verified CFD procedure, have been carried out to estimate the turbine performance for a turbine with flexible composite blades, and then the results were compared with those for rigid blades.

조류발전 터빈의 효과적인 설계를 위해서는 날개의 변형을 고려한 해석이 필요하다. 날개에 가해지는 유체 하중은 날개 구조를 변형시키고, 터빈의 성능에 영향을 초래한다. 본 연구에서는 수평축 조류발전 터빈의 단독성능을 해석하는 전산유체역학 해석 절차를 개발하였다. 개발한 절차를 이용하여 조류발전 터빈의 성능을 예측하였고 실험결과와 비교하여 검증하였다. 검증된 전산유체역학 방법을 이용하여 복합재 터빈 날개에 대한 유체-구조 연성해석을 수행하였고 강체로 이루어진 터빈 날개에 대한 전산유체역학 해석 결과와 비교하였다.
