We know that a divergence-free field that undergoes advection isn’t necessarily still divergence-free, and yet we know that the Navier-Stokes equations for impressible flow represent divergence-free velocity fields, so therefore we have our answer about what in nature prevents the velocity field from becoming divergent: pressure! For example, the Navier–Stokes equations, a set of nonlinear PDEs that describe the motion of fluid substances, can lead to turbulence, a highly chaotic behavior seen in many fluid flows. $$ This means that the pressure is instantaneously determined by the velocity field (the pressure is no longer an independent hydrodynamic variable). - isentropic.
