Abstract:Siemens Combustion Research and Development has conducted a physical experiment in which the air-fuel mixing has been visualized using laser induced fluorescence. To gain further insight into the accuracy of numerical modelling this physical experiment is desired to be replicated using a cold transient large eddy simulation of the full geometry. In order to understand the suitability of Open Source meshing software, SnappyHexMesh, which is OpenFOAM’s native mesher, is to be used. A full 3D mesh has been created of the hybrid burner inside the test rig. Alongside this mesh the cold transient large eddy simulation has been prepared by defining all boundary conditions and run-time processing routines. The simulation has been made ready to run on either a multi-core work station, the Siemens Cluster or the Julich Super Computing center. Side products are Matlab scripts that greatly increase the ease of meshing in snappyHexMesh and allow for mesh size estimations to prevent unnecessary long meshing times. Both the mesh and simulation preparations have been realized. The suitability of snappyHexMesh for complex projects like these seems prohibited to interns. This is because snappyHexMesh and the steps to realize a mesh using it, requires a lot of on the fly solutions which are time consuming.
