The design and analysis of high-speed aeropropulsion concepts requires a fundamental accounting of unsteady flow behavior as induced by shock / viscous layer interactions, fuel injection and mixing, and combustion dynamics.   This talk will discuss the development of several computational fluid dynamics techniques and modeling strategies suitable for high-fidelity analyses of such effects, both at a component level and as part of a ‘tip-to-tail’ simulation strategy.   These include large-eddy / Reynolds-averaged Navier-Stokes simulation methods for wall-bounded turbulent flows in configurations influenced by multiple solid surfaces, phase-interface capturing techniques for simulating primary atomization, phase-transition modeling for supercritical fuels injection, and immersed-boundary methods for rendering of complicated, possibly moving, objects.   Examples pertinent to compressible, reactive flows encountered in aero-propulsion systems will be presented, and future directions for research in this scope will be outlined.
