H2020 ENODISE: RWTH Numerical Aeroacoustic Database Configuration B1

<p>This RWTH dataset contains numerical data for aerodynamics and acoustics of configuration B1, which was defined in the H2020 ENODISE project (<a href="https://www.vki.ac.be/index.php/about-enodise">https://www.vki.ac.be/index.php/about-enodise</a>). In this configuration, three 6-bladed XPROP-S propellers are installed side-by-side on the leading edge of a wing with an airfoil shape of NLF-Mod22(B).</p> <p>The investigated operating point is:</p> <ul> <li>The incoming flow velocity <em>U&infin;</em>&nbsp;= 30 m/s, the wing angle of attack&nbsp;<em>AoA </em>= 2 deg, the propeller advance ratio <em>J</em> = 0.8, and the relative blade phase angle between propellers <em>∆&Phi; </em>= 0.</li> </ul> <p>Wall-resolved Large eddy simulations (LES) of the configuration are performed based on the multiphysics flow solver m-AIA of RWTH.&nbsp; The far-field noise is predicted by the Ffowcs-Williams and Hawkings (FW-H) method. The data set contains the time-averaged aerodynamic results predicted by the LES simulation and the aeroacoustic results calculated by the FW-H method.&nbsp;It should be noted that the aeroacoustic data is only a preliminary result&nbsp;and it will be updated soon.</p> <p>More details of the simulation and measurement setups are explained in the attached document ENODISE_B1_RWTH.pptx.</p>
