CFD renewables

Computational Fluid Dynamics (CFD) methods are used in many industries as design and optimization tools. Manchester is world leading in both CFD and Turbulence modelling. An objective of ongoing research is to develop CFD for design and optimization of tidal stream turbines.

Existing open source codes have been further developed to simulate the loading of tidal stream turbines due to large-scale turbulence and waves. Ongoing numerical work involves resolving the rotor of a rotating three-bladed turbine, modeling combined current and wave loading and simulating large scale turbulence beneath a free surface to represent measured conditions at a tidal stream deployment site. These massively parallel simulations are conducted using CODE_SATURNE.

Numerical models

A range of numerical models are also employed to analyse specific problems smooth particle hydrodynamics (SPH) has been developed to simulate response of devices to extreme wave loading, and linear wave theory (WAMITTM) and spectral wave models (SWAN) employed to study the response and energy yield of arrays of devices.

Sponsor

This research is currently funded by EDF, the Energy Technologies Institute and the EPSRC. Field trials are ongoing as part of the ReDAPT project to evaluate the accuracy of massively parallel CFD for prediction of unsteady loads.
