H2020 ENODISE: ONERA Numerical Aeroacoustic Database Configuration A2-Ducted

This database contains the numerical results obtained by ONERA on the configuration A2-ducted of the H2020 ENODISE project. In this configuration, a ducted propeller is placed above an S-plate to ingest an adverse pressure gradient boundary layer in a partially buried configuration. The present results can be compared to the measurements carried out by the University of Bristol. All following parameters are kept constant in the present simulations: Free-stream velocity <em>u_inf</em> = 32 m/s, Propeller tip clearance <em>d/D</em> = 0.002, Propeller position inside the duct <em>x/D</em> = -0.0627. Five simulations have been realized by varying the installation (with or without the S-plate) and the propeller rotation speed: Isolated propeller (without the S-plate), <em>N</em> = 6000 rpm, 8000 rpm, 11000 rpm, Installed propeller (with the S-plate), <em>N</em> = 6000 rpm, 8000 rpm. The predictions were obtained using the ProLB solver which is based on the Lattice Boltzmann method (http://www.prolb-cfd.com/). Aerodynamic and acoustic results are provided for each simulation. One-dimensional results are saved into ASCII column files (<em>.dat</em> extension) while geometry and raw flow extractions are saved into HDF5 CGNS files (<em>.cgns</em> extension). <em>README.txt</em> files are included for detailed description of the data.
