Tidal stream turbines: With or without a Gearbox?

Ocean Engineering, 2018
Abstract This paper proposes a review-based comparative study addressing the critical issue of tidal stream turbine drivetrain options. Indeed, tidal stream turbines are still in development stages with few industrial project deployments. Their technology is not as mature as wind turbine technology, while facing immersion constraints where have to ...

Numerical Investigation of an Optimised Horizontal Axis Tidal Stream Turbine

Volume 10: Ocean Renewable Energy, 2019
Abstract A tidal stream turbine was designed using one of the optimised hydrofoils, whose lift-to-drag ratio at an angle of attack of 5.2 degrees was 4.5% higher than that of the reference hydrofoil. The incompressible Reynolds-averaged Navier Stokes equations in steady state were solved using k-ω (SST) turbulence model for the reference

Reliability analysis of rotor blades of tidal stream turbines

Reliability Engineering & System Safety, 2014
Abstract Tidal stream turbines are used for converting kinetic energy of tidal currents into electricity. There are a number of uncertainties involved in the design of such devices and their components. To ensure safety of the turbines these uncertainties must be taken into account.

Simulation of Tidal Stream Turbine Working Near Free Surface

Applied Mechanics and Materials, 2013
The tidal stream kinetic energy can be abstracted by the horizontal axial turbine, and most concentrate closing to seaside, where the tidal stream turbine must work near the free surface. The interaction between wave surface and the turbine will affect the turbine performance.

Optimization and Flow Analysis of Ducted Tidal Stream Turbine

Advanced Materials Research, 2013
Efficiency of the tidal stream turbine with thin-wall axisymmetric ducts was numerically simulated. The ducts design parameters of diffuser curves, expansion ratio and duct length were simply optimized. The results showed that the duct of second order diffuser curve, expansion ratio of 2.25 and a length-diameter ratio of 1.2 has the best performance ...
