Abstract

Abstract

By using Lagrangian method,the flow properties of a dusty-gas point source in a supersonic free stream were studied and the particle parameters in the near-symmetry-axis region were obtained.It is demonstrated that fairly inertial particles travel along oscillating and intersecting trajectories between the bow and termination shock waves.In this region,formation of "multi-layer structure" inparticle distribution with alternating low-and high-density layers is revealed.Moreover,sharp accumulation of particles occurs near the envelopes of particle trajectories.
