Abstract
The interaction of a jet from a 60 Ibf thruster positioned on the side of a small rocket, with the rarefied atmosphere between altitudes of 80 to 160 km is studied numerically. The direct simulation Monte Carlo method was applied to model the three-dimensional jetatmosphere interaction. Chemical reactions between free stream and plume species were included in the simulations. Both uniform and non-uniform conditions were used at the thruster exit. A Navier-Stokes solver is used to calculate flow inside the thruster and in the near field of the plume. A two-stage numerical strategy was then used to calculate the plume, with sequential computations of an axisymmetric plume core flow and threedimensional plume-freestream interaction. The impact of rocket velocity and. altitude on the plume-atmospheric interaction in terms of species produced by chemical reactions that can contribute to UV and MWIR radiation is examined.
