The solid-liquid two-phase flow around a circular cylinder is simulated to make clear the particle motion in the wake region of the cylinder by using a vortex method proposed in a prior paper. The Karman vortex is calculated under two-phase flow conditions. The amplitude of the oscillation in the cross-stream direction is smaller than that under single-phase flow. The particle concentration is found low near the Karman vortex.
