Résumé

This experimental study investigates the rheological and viscoelastic properties of ice slurries to better
understand their flow behavior in secondary refrigeration systems. Ice slurries based on a 10% monopropylene
glycol solution with ice fractions of 11%, 20%, 35%, and 44% were analyzed using vane rheometry. At low
ice fractions, the slurries exhibit moderate shear-thinning behavior, with a viscosity increase above 45 s⁻¹
attributed to inertial effects. As ice fraction increases, the pseudoplastic character becomes more pronounced.
The 35% slurry shows a quasi-Newtonian plateau at high shear rates, indicating stable flow, whereas the 44%
slurry exhibits transient viscosity variations that may promote flow instabilities. Viscoelastic analysis reveals
a gel-like response at low strain, which strengthens with increasing ice content, as the transition to viscousdominated
behavior shifts to higher strain. Overall, an optimal balance between flowability and structural
stability is identified for the 35% slurry.
