Abstrakt:
The paper deals with the determination of the terminal falling velocity of solid spherical
particles moving slowly through an unbounded time-independent purely viscous
Carreau liquid. The relationships based on the Carreau four-parametric viscosity model
are given for calculation of a sphere terminal velocity falling in the creeping flow
region. The comparison of terminal velocities calculated according to these
relationships with those obtained experimentally is presented. In experiments, the
terminal velocity of spheres in the aqueous solutions of polymers was measured. A good
agreement between the calculated and experimental values of terminal falling velocities
was found.
