  Extending a previously developed two-phase equation of state, we simulate
head-on relativistic lead-lead collisions with fluid dynamics, augmented with a
finite-range term, and study the effects of the phase structure on the
evolution of the baryon density. For collision energies that bring the bulk of
the system into the mechanically unstable spinodal region of the phase diagram,
the density irregularities are being amplified significantly. The resulting
density clumping may be exploited as a signal of the phase transition, possibly
through an enhanced production of composite particles.
