    Abstract

    This paper will discuss our continued simulation of flowfields related to ducted launcher system interactions. The simulations are performed using the CRAFT Navier-Stokes code and now include the effects of afterburning chemistry and particulate nonequilibrium. The flow inside a ducted launcher is highly three-dimensional and the erosion of thermal protective materials is of significant concern. Erosion results from particle impingement whose prediction is facilitated by the availability of a new upwind/implicit finite-volume Eulerian solver. The specialized features of CRAFT oriented to the simulation of these flowfields will be discussed and a number of predictions will be described which illustrate the complexities of this interaction problem, with an emphasis on two-phase flow aspects. Recent studies of the impingement flowfields produced by firing of solid propellant motors at flat plates in support of ablative materials research will be discussed.
