Anemometer F460

— pimpleFoam, dynamic mesh, six degree of freedom, flow-induced rotation —

As the flow-induced rotation is a unique and high interesting topic, Tobias created a new training case. Here, an anemometer of type F460 was investigated. The test case is based on a publication that is included in the tar file. The »dynamicMeshDict« includes a lot of comments to introduce one to the different keywords that are needed for the set-up. However, it is worth mentioning that the rotor is starting to rotate based on the fluid flow, but Tobias never ran the case completely. As it is a 3D model, including tiny numerical cells, the calculation time is too long on Tobias' old computer. However, as the case was already created, it is worth to share it with the community.


— After four days of numerical analysis, Tobias stopped the calculation —

The case set-up, especially the inertia matrix and the values used in the »dynamicMeshDict« are derived from the CAD software Salome®. The case is identical to the »Vertical Axial Wind Turbine« tutorial except that one is investigating into a 3D model. Please do not hesitate, if you think the set-up of the case is wrong or if there is a better solution of analyzing flow-induced rotation regarding the numerical point of view. However, the case shows one how to set-up the arbitrary mesh interface AMI and how the six-degree-of-freedom (6-DoF) is used.

Over the last ten years, Tobias tried to publish a wide range of different materials related to OpenFOAM® and CFD. You know it much better than he does if the content is worth to be supported. If you want to thank Tobias for the work he did, feel free to tell the community your opinion about the work Tobias Holzmann is doing or you can email your thoughts directly to »This email address is being protected from spambots.

Keep in mind that the work that was done here took much time, and it is not self-evident that Tobias Holzmann shares all his work, knowledge, and attitude for free and keep the data up to date. Hosting the material, updating the data, and keeping up interesting work for the community does take much time and also money. Supporting Tobias can be done by donating any amount you would like to give or help him with his projects.

The available training cases are tested and built for different OpenFOAM® versions. During the tests, only the OpenFOAM Foundation version of OpenFOAM® was used. Furthermore, the following software packages are required for most of the training cases: Salome®, ParaView®, and for optimization tasks one also needs DAKOTA®. The cases might work with the ESI version of OpenFOAM® too (not tested). Additionally, there is no support for Windows-based OpenFOAM® versions.
