FURTHER WORK
The next step in the process is to map roughness data to the modelled terrain. Such data is also freely available online, however it is based on a slightly larger resolution scale making a direct application of the data difficult without prior post processing. Once both the elevation and roughness data have been obtained they must be processed using Star CCM+ (a CFD software) to formulate a 3D CAD representation of the area and begin analysis of wind flow.
A wind rose diagram represents the frequency of occurrence and the amplitude of wind in a given area as measured by a wind mast. The example diagram on the left shows that this would be in the South-West direction with wind speeds reaching 3.6 m/s. This distribution of wind speeds is used to test the model and record its response.
Once the model is complete, the wind speed would be applied using the boundary conditions obtained from the larger mesoscale model. This will give a detailed analysis of the wind flow in the area. Finally WindSim will be used to assess the accuracy of this CFD model based on real world inputs from known wind masts. |
