Abstract:

An experimental investigation was conducted to determine the drag coefficient of particles in flow regimes encountered in a rocket nozzle. The acquisition of these data leads to more reliable predictions of nozzle performance inefficiencies owing to gas-particle flow. The Mach number-Reynolds number regime traversed by a particle in a rocket nozzle is described.
