Numerical Analysis on Effects of the Contoured Endwall on the Three-dimensional Flow Characteristics in a Turbine
끝벽의 형상이 터빈 캐스케이드내 3차원 유동특성에 미치는 영향에 관한 전산해석
Abstract
The objective of this study is to document the secondary flow and the total pressure loss distribution in the contoured endwall installed linear turbine cascade passage and to propose an appropriate height of the contoured endwall which shows the best loss reduction among the simulated contoured endwall. In this study, three different contoured endwalls have been tested which have different height. This study was performed by numerical method and the result showed the contoured endwall which has the height of
