Abstract
A two-fluid model was applied to simulate compressible two-phase flow in JPL(Jet Propulsion Laboratory) nozzle and supersonic jet two-phase flow. And, the interactional mechanism of gas phase and particle phase, rules of particles flowing at different sizes were studied. Program "Solve2D" solving two-dimensional axisymmetric compressible two-fluid model with body-fitted coordinate system was developed. The program was used to solve gas phase Navier-Stokes (N-S) equations with k-ε turbulence model. For particle phase, Euler equations were solved. Two phases were coupled through source terms. Gas-particle two-phase flow field of JPL nozzle and jet were studied under different particle mass percentages and different particle sizes.
