Abstract
In this paper, we consider the Cauchy problem of the 3D incompressible Keller–Segel–Navier–Stokes equations with partial diffusion, namely we remove the diffusion . Using the damping effect of the growth term
and the geometry of axisymmetric flow without swirl, we prove the global existence of weak solutions for the system.
