Abstract: |
<strong>This repository releases the 284 million cell case shortly described in the aforementioned paper and consists of a DDES CFD simulation of a cycloidal rotor which was scaled to test the limits of the OpenFOAM software when simulating rotating machinery.</strong> <br> <i>The intent is to provide the community a publicly available testcase to favor further improvements to the OpenFOAM code, especially in terms of <b>HPC scalability</b>.</i> <br> <br> A short user manual is given in the <b><a href="https://darus.uni-stuttgart.de/file.xhtml?fileId=198103">00_README.md</a></b> file. <br> The other files are as follow (switch from table to tree view if you want to see the files sorted into folders): <br> <ul> <li><b>01_ReadyToRunCase.tar:</b> this file allows any user to restart the simulation where it was stopped without necessarily having to decompose the domain or proceed to any preprocessing step</li> <li><b>02_needed_OF_libs-v2206.tar.bz2:</b> these OpenFOAM librairies are needed to run the test case; tested on v2206, but will likely work with other versions as well</li> <li><b>03_generator.tar:</b> files and scripts to build the case from zero</li> <li><b>04_fullBlade0.pw:</b> this is the original blade mesh from Pointwise and can be used to reconstruct the case using the 03_generator.tar archive and running the given scripts</li> <li><b>04_halfBlade0.pw:</b> this is the original HALF blade mesh from Pointwise and can be used, for exemple, to modify the blade mesh before rerunning the case with a different grid resolution</li> <li><b>05_fullBlade0.gg:</b> mesh exported into gridgen format</li> <li><b>05_fullBlade0_struct.cgns:</b> blade exported into structured cgns format</li> <li><b>05_fullblade0_unstruct.cgns:</b> blade exported into unstructured cgns format</li> <li><b>05_fullblade0_withDatabases.gg:</b> blade exported into gridgen format and keeping the blade surface database</li> </ul> <br> Each tar archive is accompanied by a .tar.list file giving a quickly accessible archive content. <br> <br> The simulated rotor has 4 blades, a radius of 84.25 mm and turns at 1695 RPM. The maximum pitch angles of the upper and lower paths are 35° and 38°, respectively, and they occur at position 100° and 277°, respectively. <br> Simulation setups of the same rotor using lower cell counts varying between 12 to 24 million cells and being defined according to the praxis for URANS simulation are available in the following repository: https://doi.org/10.18419/darus-2812 <br> The case is ran using OpenFOAM (pimpleFoam) on the HLRS-Hawk supercomputer. <br><br> A thorougher description of the case is available in the upcoming paper which was submitted to the Journal of the American Helicopter Society, <b>request preprint here:</b> <i>https://www.researchgate.net/publication/369473318_Parametric_Aerodynamic_Study_of_a_3D_Printed_Cycloidal_Rotor_Prototype_Designed_for_the_Best_Figure_of_Merit</i> <br><br> Videos of the simulation are available for: <ul> <li>blade surface pressure: <a href="https://youtu.be/jJQBeXSGawI">https://youtu.be/jJQBeXSGawI</a></li> <li>wake vorticity: <a href="https://youtu.be/_vl5uO_mVVo">https://youtu.be/_vl5uO_mVVo</a></li> </ul> |
