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.

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.

gThe 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.
