Rotordynamic forces significantly impact pump performance, particularly due to eccentricity in components.
Positive cross and direct forces arise from non-axisymmetric pressure inside the seal path in both models.
Steady 3D RANS simulations revealed critical differences between eccentric seal and eccentric impeller models.
Accurate predictions of rotordynamic forces are essential for rigorous stability analysis of pump systems.
