Abstract

Numerical simulations on gas-solid two-phase flow in axisymmetric shock induction controlled vectoring exhaust nozzle were carried out using particle trajectory model. The characteristics of deposition were studied on particles' diameter changed from 1μm to 100μm. The result indicates that the particles in the main flow mainly deposited in the area of divergent part and the throat, and with the accretion of particle diameter, the deposition area extends, the deposition rate increases. Large particles in the secondary flow could ablate the wall. The ablation from particles in secondary flow must be considered into the design of heat-resistant construction.

Key words： fluidic thrust vector nozzle; two-phase flow; deposition; numerical simulation
