An effective method for predicting aerodynamic noise for wind turbine flatback airfoils

Section 1 of the full paper explains our prediction method mentioned in the title, which we believe is effective and whose core is: using two-dimensional Reynolds-averaged Navier-Stokes equations, we calculate the flow around a conventional sharp trailing edge airfoil and its flatback version employing γ-Rẽ _θt transition prediction method based on SST turbulence model; the aerodynamic noise of the flatback airfoil is then computed using hybrid method combining the former CFD results with the Ffowcs Williams-Hawkings(FW-H) equation. Section 2 presents both aerodynamic and acoustic results in Figs. 3 through 9, and analyze most of them, showing preliminarily that the calculated results are in good agreement with experimental data; thus section 2 indicates that our method is successful for predicting aerodynamic noise for wind turbine flatback airfoils.
