Abstract:
The simulation of wind turbine aerodynamics can be improved with more physically realistic models than the ones currently in use in engineering
practice. In this report the mathematical and numerical aspects and
the practical use of a new wind turbine aerodynamics simulation module
is described.
The new simulation code is based on non-linear lifting line vortex wake
theory which is a more accurate model for rotor wake physics; an important
aspect in wind turbine load simulations. The new model is verified for
some test cases with analytical solutions. Wake dynamics are shown to
behave as anticipated. The new simulation module, designated AWSM, is
expected to substantially
reduce the number of uncertainties that accompany currently used blade-element-momentum
methods. To assert the quality of AWSM resulta a comparison with experimental
data is recommended. Numerical tests should be performed. Numerical
tests should be performed to investigate the influence of AWSM simulation
parameters on the computed results. Further functionality extensions
and algorithm optimimizations are suggested.
