Research Abstract

A numerical method with a new hybrid model which combines the Carreau model for treating shear-thinning properties with the FENE.CR model for treating elastic properties was established for computing non-Newtonian gas-liquid flows. The motion of a bubble or drop rising in shear-thinning viscoelastic fluids and drop deformation and breakup in shear-thinning viscoelastic shear flows were computed using the established method. Numerical results revealed that both elastic and shear-thinning properties had synergistic effects on the bubble or drop motion.
