Abstract: This paper is concerned with the Cauchy problem for a 3D fluid-particle interaction model in the so-called flowing regime in $\mathbb{R}^{3}$. Under the smallness assumption on both the external potential and the initial perturbation of the stationary solution in some Sobolev spaces, the existence and uniqueness of global smooth solutions in $H^{3}$ of the system are established by using the careful energy method.

Key words: fluid-particle, flowing regime, global existence
