In everyday life we encounter many different kinds of fluids, like
water and honey consist of small molecules only and have no large internal
structures and thus have a simple viscous behavior. This means that their
viscosity (and also the other material functions) depends only on the
temperature and pressure, but not on the chosen flow. These fluids are called
Newtonian. However, many fluids do not show such a simple behavior. This
is generally due to the presence of large internal structures, which are often
caused by large molecules. The viscosity of these fluids depends on the
deformation rate. Those types of fluids are therefore said to have a non-
Newtonian behavior. Some other fluids show elastic behavior, those fluids
said to be a viscoelastic fluids. Examples of such fluids are paints, dough,
yogurt, clay, etc. Obviously, polymer solutions belong to this category.
