Abstract
This study simulates the collision between a vortex ring and an ensemble of small glass particles.The vortex ring, convecting with the self-induced velocity in a quiescent air, collides with the particles. The Reynolds number for the vortex ring is 2600, and the particle diameters are 50 and 200, um. The Stokes number St for the 50μm particle is 0.74, while the St value for the200μm particle is 11.4. The simulation reveals the particle motion depending on the Stokes number. It also highlights the effect of the Stokes number on the behavior of the vortex ring.
