Characterising the wake of horizontal axis marine current turbines
Characterising the wake of horizontal axis marine current turbines
An experimental and theoretical investigation of the flow field around small-scale mesh disk rotor simulators is presented. Wake characteristics of the rotor simulators have been measured in the 21m tilting flume at the Chilworth hydraulics laboratory, University of Southampton. A three-dimensional Eddy-viscosity numerical model based on an established wind turbine wake model has been modified to account for the change in fluid and the presence of a bounding free surface. This model shows good agreement with the measured experimental data and further work will be conducted to refine the model.
This work has been conducted as part of a DTI-funded project to develop a numerical modelling tool which can predict the flow onto a marine current turbine within an array. The work presented in this paper feeds into this project and will eventually assist the layout design of arrays which are optimally spaced and arranged to achieve the maximum possible energy yield at a given tidal energy site.

Abstract
An experimental and theoretical investigation of the flow field around small-scale mesh disk rotor simulators is presented. Wake characteristics of the rotor simulators have been measured in the 21m tilting flume at the Chilworth hydraulics laboratory, University of Southampton. A three-dimensional Eddy-viscosity numerical model based on an established wind turbine wake model has been modified to account for the change in fluid and the presence of a bounding free surface. This model shows good agreement with the measured experimental data and further work will be conducted to refine the model.
This work has been conducted as part of a DTI-funded project to develop a numerical modelling tool which can predict the flow onto a marine current turbine within an array. The work presented in this paper feeds into this project and will eventually assist the layout design of arrays which are optimally spaced and arranged to achieve the maximum possible energy yield at a given tidal energy site.
