Tobias once had an interesting discussion with his former colleague, Dr. Jan Bohacek, at the Montanuniversität Leoben. There they discussed about windscreens and fluidic oscillator systems. Sometimes, fluid dynamics without any moving parts do have exciting phenomena.
Computational Fluid Dynamics gives insight into exciting phenomena
The following example can be used to explain different and complex fluid phenomena. The operation of the fluidic oscillator uses geometrical properties to start an oscillating fluid stream. The fluidic oscillator is used for windscreen cleaning devices on cars or trucks because no motion of mechanical parts is needed. The frequency is related to the size of the channels and the mass flux going through the fluidic oscillator. The case itself is meshed by using the in-house mesher, namely snappyHexMesh, and is further modified for 2D purposes. Additionally, a passive scalar transport equation is built on the fly by using the object function libraries. A source term is added by using the fvOptions options.

The available OpenFOAM® training cases are tested and built for different OpenFOAM® versions (not distributions) on a Linux machine. 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 the open-source software DAKOTA®. The OpenFOAM® cases might work with the ESI version of OpenFOAM® but it is not supported. For the OpenFOAM® extend project, the training cases will probably not work as the code diverged too much. Additionally, there is no support for Windows-based and MAC-based OpenFOAM® versions.

Share the work on Your social network
Tobias would be grateful if you share his work on your social network in order to keep the OpenFOAM® community up to date. Furthermore, sharing the work will avoid that people investigate into topics, that are already prepared for your study such as the examples provided by Tobias Holzmann.
