Development of a RANS and LES/RANS flow solver for high-speed engine flowpath simulations

Edwards, Jack R.; Fulton, Jesse A.

The development of a reactive flow solver suitable for large-scale simulations of high-speed engine component flow fields is described in this paper. The intent is to mature an existing flow solver, North Carolina State University’s REACTMB, into a production-level tool suitable for test and evaluation (T&E) activities. The computational framework is based on the combined use of Reynolds-averaged Navier-Stokes (RANS) methods and large-eddy simulation (LES) strategies, with the former used to examine system-level effects and the latter used for detailed component studies. Specific modifications that extend the capabilities of REACTMB (bleed modeling, eddy-dissipation combustion modeling) are described, as are methods for coupling flow solutions with established 1D system performance tools.
