11. Her fields of specialization are on nonlinear waves and non-Newtonian fluids . 12. Therefore, blood behaves as a non-Newtonian fluid in such blood vessels. 13. Rheologically speaking fiber suspensions are non-Newtonian fluids , and can display normal stress differences. 14. In fact, with the right particles, even a Newtonian fluid can exhibit non-Newtonian behavior. 15. Even for a Newtonian fluid , the viscosity usually depends on its composition and temperature. 16. This is modeled using power law for generalized Newtonian fluids . 17. Non-Newtonian fluids exhibit a variety of different correlations between shear stress and shear rate. 18. A dilatant is a Non-Newtonian fluid where the shear viscosity increases with applied shear stress. 19. Newtonian fluids can be characterized by a single coefficient of viscosity for a specific temperature.20. Non-Newtonian fluids have a more complicated, non-linear stress-strain behaviour.
