This work presents a high-fidelity shape optimization framework based on computational
fluid dynamics (CFD). The presented work is the first comprehensive curved tip shape study …

Winglets have been used to augment the power extraction of Horizontal Axis Wind Turbines
(HAWT). However, despite some understanding on the way they affect the aerodynamics of …

Twisted Darrieus water turbine is receiving growing attention for small-scale hydropower
generation. Accordingly, the need for raised water energy conversion incentivizes …

This paper presents an overview of wind turbine research techniques including the recent
application of hybrid testing. Wind turbines are complex structures as they are large, slender …

This work revisits the theoretical limits of one degree-of-freedom wave energy converters
(WECs). This work considers the floating sphere used in the OES Task 10 WEC modeling …

The design of turbine blade is a vital issue in the performance of horizontal axis ocean
current turbine (HAOCT). The purpose of this paper is to conduct the performance analysis …

Tip vortices are observed downstream of the flow past the three-dimensional hydrofoils used
in propeller, wind and tidal turbines and they largely determine the forces exerted on such …

The tonal noise generated at the tip is a major contribution to the aerodynamic noise
generated by three-dimensional airfoils. One way to reduce this noise is the use of end …

Nowadays, numerical simulations of wind turbines based on the Reynolds-averaged Navier–
Stokes (RANS) formulation are becoming, in terms of computational cost, increasingly more …

Rüzgar enerjisi, dünyada en çok kullanılan yenilenebilir enerji kaynaklarından biri olup,
enerjide dışa bağlılığı yüksek olan Türkiye için büyük bir öneme sahiptir. Rüzgar …
