Cosine blade element distribution issue
In VAWT mode, in lifting line simulations in QBladeCE with cosine blade sections, the blade element distribution in the output file does not match the actual locations of the blade sections in the turbine.
Hello,
in general, the blade discretization for BEM or LLT simulations can be independent from the blade discretization that has been defined in the blade design module. A linear interpolation is carried out to obtain the respective Cl/CD coefficients from the stations that are specified in the blade design module.
However, I am not sure if this answers your issue. Could you please clarify exactly what you are referring to with: “the actual locations of the blade sections in the turbine” and “the blade element distribution in the output file”. Could you maybe even attach an example via a screenshot or file?
Thanks and BR,
David
