FLOW OF COMBUSTION PRODUCTS CONTAINING CONDENSED-PHASE PARTICLES OVER A RECESSED VECTORABLE JET NOZZLE

The fl ow of combustion products containing condensed-phase particles over the recessed vectorable nozzle of a solid-propellant rocket motor was investigated with the use of the Reynolds-averaged Navier–Stokes equations, equations of the k–ε model of turbulence, and the Lagrange approach. The fi elds of fl ows of combustion products and the mechanical trajectories of condensed-phase particles in the charge channel, the prenozzle space, and the nozzle unit of this motor were calculated for different angles of swing of the nozzle. The formation of vortices in the gas fl ow in the neighborhood of the downstream cover of the nozzle and their infl uence on the movement of particles  different in size were considered.
