In this paper, we examine the regularized B ́enard problem in porous media within three- dimensional case. We consider the regularized B ́enard problem with damping a|u|2β u. The results hold in the context of periodic boundary conditions. We prove the existence of weak solutions for any β ≥ 0 and establish uniqueness of the weak solution for any 5/4 ≤ β ≤ 2.
