H2020 ENODISE: RWTH Numerical Aeroacoustic Database Configuration B1

This RWTH dataset contains numerical data for aerodynamics and acoustics of configuration B1, which was defined in the H2020 ENODISE project (https://www.vki.ac.be/index.php/about-enodise). 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).

The investigated operating point is:

• The incoming flow velocity U∞ = 30 m/s, the wing angle of attack AoA = 2 deg, the propeller advance ratio J = 0.8, and the relative blade phase angle between propellers ∆Φ = 0.

Wall-resolved Large eddy simulations (LES) of the configuration are performed based on the multiphysics flow solver m-AIA of RWTH.  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. It should be noted that the aeroacoustic data is only a preliminary result and it will be updated soon.

More details of the simulation and measurement setups are explained in the attached document ENODISE_B1_RWTH.pptx.
