The renewal energy technologies are increasingly popular to ensure future energy sustenance
and address environmental issues. The tides are enormous and consistent untapped resource of renewable
energy. The growing interest in exploring tidal energy has compelling reasons such as security and
diversity of supply, intermittent but predictable and limited social and environmental impacts. The tidal
energy industry is undergoing an increasing shift towards diffuser augmented turbines. The reason is the
higher power output of diffuser augmented turbines compared to conventional open turbines. The purpose
of this study is to present a comprehensive review of diffuser augmented horizontal axis tidal current
turbines. The components, relative advantages, limitations and design parameters of diffuser augmented
horizontal axis tidal current turbines are presented in detail. CFD simulation of NACA 0016 airfoil is
carried out to explore its potential for designing a diffuser. The core issues associated with diffuser
augmented horizontal axis tidal current turbines are also discussed.
Key words: Diffuser Augmented Tidal current Turbine (DATT), open/naked turbine, shrouded/ducted turbine, tidal current device, tidal current turbine, tidal energy ,
