What is the likely nature of fluid motion in Venus's core, given the lack of a strong global magnetic field?

Answer

Turbulent and chaotic.

Because Venus lacks a sufficiently fast spin, the Coriolis forces are too weak to impose global structure, resulting in core motions that are likely turbulent and chaotic rather than organized for generating a planet-wide dipole field.
