v1.4

• Core:
  • This version introduces WakeDeflection models. This replaces and generalizes the YawedWakes wake frame, such that now any choice of wake frame can be combined with yawed wakes, for example streamlines or dynamic wakes. The wake deflection model is selected through the parameter wake_deflection or the algorithm and then applies to all wakes.
  • Wake models, wake deflections or wake superpositions can now induce a horizontal rotation of the waked wind vector. This is realized by inhternally switching from a (WS, WD) description to a UV vector, and vice-versa at the end of calculations.
  • A new abstract class WindVectorWakeSuperposition was instroduced for the purpose of handling UV wind wake effects.
• Inputs:
  • New states WeibullSectors, reading and interpreting spatially homogeneous Weibull scale and shape parameters for wind direction sectors, from csv or nc files
• Models:
  • New wake deflection model Bastankhah2016Deflection, replacing the previous YawedWakes wake frame. Notice that this model does not modify the wind speed deficit or the wind direction in the wake, it only changes the wake path. Meant to be used together with the Bastankhah2016 wake model.
  • New wake deflection model JimenezDeflection, which bends the wake and optionally also rotates the waked wind vector along the path. If that option is chosen, this model requires a vector type superposition of the wind deficit.
  • New wake deflection model NoDeflection, which switches off wake bending and should be used if no yaw misalignment occurs in the simulation (default).
  • New wake superposition model WindVectorLinear, realizing linear vector type wind vector superposition.
