30 <strong>WindSim</strong> ASTurbulent kinetic energy turbulent kinetic energy, KE (m 2 /s 2 )Turbulent intensity turbulent intensity assuming isotropic turbulence,100*SQRT((4/3)*KE)/SQRT(UCRT 2 +VCRT 2 ) (%)Turbulent dissipation rate turbulent dissipation rate, EP (m 2 /s 3 )Pressurerelative pressure minus hydrostatic term (Pa), the relativepressure has a value equals to zero at the outlet of the domainIn this tutorial we will extract a scalar and a vector variable. Specify for example Windvelocity 3D (u,v,w), at 50 m height and Turbulent Kinetic energy at 50 m height. Run themodule and have a look at the report. The Properties panel looks now like in Figure 18 whilein Figure 19 and 20 are respectively reported the speed 3D vector and the turbulent kineticenergy.Note that the height for the extraction of results has been left to the default value which is 50m above ground level; several heights can be defined separated by semicolons. Typicalheights of interest are the hub height of the displaced turbines and the levels of the windmeasurements.It is important to remark that the results module is a tool for visualisation of the wind fieldsimulations, to see how the flow fields are affected by the terrain. The wind speeds are notby default calibrated with wind measurements. Non dimensional, normalised, plots are alsoavailable, you need to choose the desired normalization type in the property grid (see Figure17). The Wind Resources and Energy modules are used to weight the CFD with theclimatology data.
