摘要:This paper presents numerical study of the surface
curvature effects on the performance of a 3D lab scale tidal
turbine (E387) using Eppler 387 airfoil. The prescribed surface
curvature distribution blade design method is used to remove
the surface curvature discontinuity of E387 turbine and the
redesigned turbine is denoted as A7 turbine. The two turbines
are analysed using in-house BEM code and CFD RANS.
The performance of E3787 turbine obtained from BEM and
RANS match well with the experimental results from reported
literature. The A7 turbine has mildly better performance at
low tip speed ratio (1-4.25) at which the blade is partly or fully
stalled.
