Implementation and Validation of a MILES Solver for the Simulation of Supersonic Jet Flow

A new MILES (Monotonically Integrated Large-Eddy Simulation) solver has been developed for the simulation of supersonic jet flow and its acoustic properties. The solver uses a finite volume discretization together with the FCT (Flux-Corrected Transport) convection scheme. In order to validate the code, a number of benchmark runs have been performed and compared to those obtained using an FCT solver from the finite element code FEFLO [Liu et al, AIAA, 2009]. The runs use identical input flow conditions and geometry, and include a convergent-divergent nozzle with both over- and under-expanded flow.
