A three-dimensional solver for simulating detonation on curvilinear adaptive meshes

A generic solver in a parallel Cartesian adaptive mesh refinement framework is extended to simulate detonations on three-dimensional structured curvilinear meshes. second-order accurate finite volume method used with grid-aligned Riemann solvers for thermally perfect gas mixtures. Detailed, multi-step chemical kinetic mechanisms are employed and numerically incorporated splitting approach. The technique applied mapped using modified prolongation restriction operators. flux along the coarse-fine interface considered correction procedure ensure conservation of solver. numerical accuracy, robustness simulations verified validated suitable benchmark tests. new then detonation problems non-Cartesian geometries. simulation conducted propagation 90-degree pipe bend. round tube also simulated Galilean frame reference. Both rectangular mode spinning observed simulations. In addition, fundamental problem wave/boundary layer interaction studied. results show that can high-speed reactive flows efficiently by combined use mapping adaptation.
