ACMI Heat Transfer

— laplacian(DyM)Foam, snappyHexMesh, arbitrary coupled mesh interface, dynamic mesh, coupling, decoupling —

In industries there are processes in which energy is transferred between different parts that connect and de-connect. For example, in the steel production sector, molds can vibrate while the shell is cooled via water. The vibrating molds cool the liquid pool which flows through it. Such a phenomenon is exciting and has to be considered in numerical investigations. Therefore, Tobias created this kind of tutorial which shows a moving block along a fixed part.


— ACMI Boundary condition can be used for high complex dynamic motions with regions that connects and de-connects —

IThis training case demonstrates the generation of a moving, dynamic mesh that is heated-up. While the moving part is connected to the static part, a heat transfer takes place. While analyzing the training case, one will understand how the coupling interface, namely Arbitrary Coupled Mesh Interface (ACMI), is built. The generation of the ACMI incorporates several applications such as createPatch, topoSet, and createPatch. Any derivations of the case are possible to fit the requirements one needs. Furthermore, snappyHexMesh, in cooperation with flattenMash and extrudeMesh, is used to create a 2D mesh. To use the tutorial, one needs the modified solver named «laplacianDyMFoam«.

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.
