In the computational fluid dynamic analysis, engineers are using a fixed rotation set-up for the moving mesh that includes the design of the turbine. However, if one is interested in a flow-induced rotation, the six degrees of freedom library in OpenFOAM can be used to handle such analysis. Discount of 25% possible.
Arbitrary Rotating Inlet ACMI
The arbitrary coupled mesh interface (ACMI) condition is compelling if the usage of the boundary condition is well understood. The following training case builts an ACMI for a rotating inlet pipe which is connected to a larger second pipe. The set-up is tricky and needs advanced techniques and applications for the correct ACMI generation. Discount of 25 % possible.
Creation of an Arbitrary Mesh Interface (AMI)
The generation of the arbitrary mesh interface (AMI) boundary condition is used for splitting the static and dynamic mesh regions. To create such boundaries, different methods can be applied. Commonly, Holzmann CFD uses the inhouse mesher of OpenFOAM namely snappyHexMesh, to generate high valuable numerical meshes. Discount of 25% possible.
Arbitrary Coupled Mesh Interface
In engineering applications, it is common to have active parts which connect and disconnect. Using the arbitrary coupled mesh interface in OpenFOAM® allows one to use dynamic elements that connect and disconnect during the time. The usage of such boundary conditions and the correct set-up is the principal focus of this training case. Discount of 25 % possible.
Arbitrary Rotating AMI
Dynamic meshes are state of the art for engineering processes. In many cases, the numerical analysis has to be adapted to the rotation because, e.g., the multi-reference-frame (MRF) assumption does not hold anymore. To investigate into such phenomenon, OpenFOAM offers a mapping and interpolation boundary condition namely arbitrary mesh interface (AMI). Discount of 25 % possible.
2D Rotational Axis Symmetric Meshing
2D and 2D rotational axis symmetric numerical meshes are used whenever it is possible. This method is related to the savings in computational effort and simplification at all. However, there are several ways to create 2D rotational axis symmetric geometries in OpenFOAM®. For more complex designs, it is worth to analyze the following training case which uses the 3D meshing tool »snappyHexMesh« to mesh the geometry in 3D first, and afterward derive the 2D rotational axis symmetric model by using other OpenFOAM® tools such as extrudeMesh and so on.
Gin Tonic (Conjugated Heat Transfer)
Heat transfer problems, including several different regions, are state of the art simulations for CFD engineers. In each engineering application, heat transfer processes occur. Depending on the investigation, the energy transport can be one of the critical quantities such as thermal stress, temperature resistance and so on. The training case provides the correct set-up for such kind of problems and will guide the trainee through the different steps. Discount of 25 % possible.
Everybody is aware of a windscreen washer build in a car. However, most of the people think that there is a nozzle which is distributing the water onto the windscreen. This training case demonstrates the proper work of such a device. It is not a nozzle nor a mechanically driven spray generation. By using deliberate geometric designs, a fluid induced instability is generated which distributes the outcoming water stream periodically onto the object it is aimed. Discount of 25 % possible.
Vertical Axial Wind Turbine (VAWT)
Flow-induced rotations are state of the art problematics in computational fluid dynamics analysis such as wind turbines or Kaplan turbines. OpenFOAM® offers the possibility to use an existing library namely the Six Degree of Freedom (6DoF) library to model such a phenomenon. This training case will guide you through the necessary steps to simulate flow-induced rotations. The well known and structured Holzmann CFD's run script is generating the whole case automatically and therefore, you can understand and follow each step. Discount of 25 % possible.
