- Abstract:
- The numerical simulation of gas-solid two-phase flow in fluidic thrust vector nozzle based on shock wave control was carried out with a particle trajectory model. The moving trajectory of particles whose diameters are from 1μm to 60 μm was studied. The research result shows that the smaller the particle is, the better the flowing property becomes; the bigger the particle size is, the more violent the collision between the particles in the main flow and the wall in convergent region occurs; and the larger the region without any particle is, the more serious the collision between the particles in the second flow and lower wall in the nozzle becomes.
