The use of automatic partitioning in the spatial coupling of flow and structure in large models was for the first time systematically investigated in the ComFliTe project. The results were compared to the measurement data from the low-speed wind tunnel in Braunschweig (NWB). The objective was the evaluation of automatic partitioning of coupling domains with regard to their feasibility and effectiveness. To do so, different types of partitioning (number of support points, number of partitions and direction of the partition) were examined on a reference configuration. The results of the coupled calculations (e.g. distribution of pressure and deformations) were compared and contrasted with the experimental data.
In the figures shown on the right, the reference configuration DLR-F12 is illustrated as a CFD-computational model and the results of the case study are shown. The comparison of the calculated and measured Cp distribution clearly shows that the results are independent of the number of partitions, the direction of the partition and the number of support points. The method of automatic partitioning was thus confirmed using the DLR-F12 configuration as an example.
