Abstract
A numerical investigation is carried out of the flow field around a Ram Accelerator projectile running through a tube filled with a detonating gas laden with reactive solid particles. First, a mathematical model for the two-phase, chemically-reactive flow, is proposed. A TVD numerical scheme is employed, based on the resolution of two Riemann problems: a classical one for the gas phase, and a non-conventional one, for the dispersed phase. Results are presented, first for a RAM projectile flying at 6.7 km/s through a H2/O2/He mixture, and compared with recent literature data. Then, computations are made for the same conditions, but with the addition of solid hydrazine nitrate particles. It appears that the existence of sufficiently small particles improve the performance of the Ram Accelerator.
