1. However, non-Newtonian fluids are relatively common, and include thinner when sheared ). 2. Drilling mud is usually a shear thinning non-Newtonian fluid of variable viscosity. 3. For isotropic Newtonian fluids , these can be reduced to two independent parameters. 4. Blood is a non-Newtonian fluid , best studied using rheology rather than hydrodynamics. 5. Non-Newtonian fluids designed for anti-icing are not really like ketchup or honey. 6. There he expanded his research area into the field of non-Newtonian fluid mechanics. 7. In the former case, the viscosity corresponds to that for a Newtonian fluid . 8. For non-Newtonian fluids , there are different stress tensor to the shear rate tensor. 9. Newtonian fluids are the simplest mathematical models of fluids that account for viscosity.10. By contrast, stirring a non-Newtonian fluid can leave a " hole " behind.
