Summary: | <p>In this paper, an analytical wake model with a double-Gaussian velocity
distribution is presented, improving on a similar formulation by <span class="cit" id="xref_text.1"><a href="#bib1.bibx14">Keane et al.</a> (<a href="#bib1.bibx14">2016</a>)</span>. The choice of a double-Gaussian shape function is motivated by the
behavior of the near-wake region that is observed in numerical simulations and
experimental measurements. The method is based on the conservation of
momentum principle, while stream-tube theory is used to determine the wake
expansion at the tube outlet. The model is calibrated and validated using
large eddy simulations replicating scaled wind turbine experiments. Results
show that the tuned double-Gaussian model is superior to a single-Gaussian
formulation in the near-wake region.</p> |
