Numerical investigation of the erosion behavior in blades of tidal current turbine
Journal of Renewable and Sustainable Energy, 2022The blade erosion of tidal current turbine can lead to significant energy losses and affect stall behavior. To maintain good performance and prevent turbine malfunction, it is important to determine the location and rate of blade erosion caused by ...

Power production of the counter-rotating tidal current turbine, including duct effect
Ships and Offshore Structures, 2022In this paper, a counter-rotating tidal current turbine (CRTCT) with and without duct is investigated by Reynolds-Averaged Navier-Stokes (RANS) equation method. The (Shear Stress Transport) turbulence model is adopted in the steady-state simulation.

Modeling tidal turbine farm with vertical axis tidal current turbines
2007 IEEE International Conference on Systems, Man and Cybernetics, 2007A tidal current turbine is a device for harnessing energy from marine currents, and functions in a manner similar to a wind turbine. A group of tidal current turbines distributed in a site in ocean is called a tidal turbine farm. Among all tidal current energy extraction schemes, turbine farm is regarded as among the most promising turbine ...

Turbines for modular tidal current energy converters
Renewable Energy, 2019Abstract The vast potential of ocean energies is of increasing interest. Harnessing marine currents driven by the tidal cycle have triggered the development of various power conversion systems. However, the comparably high levelized cost of electricity is still the main hindrance for a faster market penetration.

Estimation of Mechanical Parameters and Tidal Current Velocity for a Tidal Turbine
IEEE EUROCON 2021 - 19th International Conference on Smart Technologies, 2021This paper presents a novel methods for the estimation of the mechanical parameters and the tidal current velocity in a Tidal Energy Conversion System. The first method is based on a Luenberger Observer including the mechanical equation of the system, and the measurement of the electric current induced by the electrical machine. Then, the estimation of

Analytical wake model of tidal current turbine
Energy, 2015Prediction of the wake structure is important to understand the lee flow of a tidal current turbine. The proposed analytical wake model consists of several equations derived from the theoretical works of a ship propeller jet. Axial momentum theory was used to predict the minimum velocity at the immediate plane of the lee wake and followed by the ...

Wake Modeling of Tidal Current Turbine Array
2019 International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET), 2019This paper presents the results of a Computational Fluid Dynamics (CFD) model of a two rotors operating in close proximity. The main purpose was to obtain a validated CFD model of scaled twin rotor laboratory turbine and to model how the wake of these two rotors will affect the performance of individual and collective turbines in future array.
