H2020 ENODISE: GPUP Configuration B Numerical Databases with Mitigation

<p>This dataset&nbsp;contains the numerical prediction for A2&nbsp;configuration&nbsp;as defined in the H2020 ENODISE&nbsp;project (<a href="https://www.vki.ac.be/index.php/about-enodise">https://www.vki.ac.be/index.php/about-enodise</a>)</p> <p>The dataset corresponds to the Band-Limited Overall Sound Pressure Level (BL OASPL) measurements obtained for Configuration B, focusing on the acoustic performance of propellers under different configurations. Two main setups were tested:</p> <ol> <li><strong>Propeller without Serrations</strong>: This configuration represents the baseline case where the propeller operates without any modifications to its trailing edge.</li> <li><strong>Propeller with Serrations</strong>: This configuration represents the case where the propeller operates with serrations at the trailing edge of the propeller.</li> </ol> <h1><strong>Setup&nbsp;</strong></h1> <ol> <li> <p><strong>Rotors</strong>: The setup involves three rotors:</p> <ul> <li><strong>Rotor_C (Central Rotor)</strong></li> <li><strong>Rotor_L (Left Rotor)</strong></li> <li><strong>Rotor_R (Right Rotor)</strong></li> </ul> <p>The Left and Right Rotors (Rotor_L and Rotor_R) are fixed at a position of <strong>x = -0.22m</strong>.</p> </li> <li> <p><strong>Axial Locations and Phase Angles</strong>: The central rotor (Rotor_C) was moved in the axial direction, and three distinct setups were investigated:</p> <ul> <li><strong>Baseline Case (&Delta;x = 0Db)</strong>: Rotor_C located at <strong>x = -0.22m</strong>.</li> <li><strong>Forward Case (&Delta;x = -0.2Db)</strong>: Rotor_C moved forward to <strong>x = -0.26m</strong>.</li> <li><strong>Backward Case (&Delta;x = +0.2Db)</strong>: Rotor_C moved backward to <strong>x = -0.18m</strong>.</li> </ul> <p>For each axial location, four phase angles were tested: <strong>0&deg;, 45&deg;, 90&deg;, 135&deg;</strong>.</p> </li> </ol> <h1>Dataset :</h1> <ol> <li> <p><strong>Total Simulations</strong>:</p> <ul> <li>Each propeller configuration (serrated and non-serrated) was tested under the three axial locations and four phase angles, resulting in a total of <strong>12 simulations</strong> for each setup.</li> <li>This results in <strong>24 simulations</strong> (12 simulations with serrations + 12 simulations without serrations)&nbsp;across all configurations.</li> </ul> </li> <li> <p><strong>Measured Parameters</strong>:</p> <ul> <li><strong>Area-averaged Bandlimited Prms</strong>: The overall sound pressure level averaged over the area, given in both linear scale and converted to decibels (dB).</li> <li><strong>Maximum Bandlimited Prms</strong>: The maximum sound pressure level observed within the band, also provided in both linear scale and dB.</li> </ul> </li> <li><strong>Script</strong> <ul> <li>Python script is provided which converts original dataset to log scale&nbsp;</li> </ul> </li> </ol>
