Abstract
AbstractThe compressible Navier‐Stokes (NS) equations are spatially discretized with the discontinuous Galerkin (DG) method and an implicit backward differentiation formula of second order is used for the temporal discretization. The Chimera method is employed to realize a simple grid generation for complex technical applications consisting of multiple parts. Therefore, non‐trivial overlapping grid areas could occur in the numerical setup which require a robust implementation of the Chimera method. The flow around two circular cylinders in tandem arrangement serves as a validation case and reveals promising results for several configurations compared to reference data in literature.
