Abstract:
|
Non-Newtonian fluids occur commonly in our world. These fluids, such as
toothpaste, saliva, oils, mud and lava, exhibit a number of behaviors that are
different from Newtonian fluids and have a number of additional material
properties. In general, these differences arise because the fluid has a
microstructure that influences the flow. In section 2 we will present a collection of
some of the interesting phenomena arising from flow nonlinearities, the inhibition
of stretching, elastic effects and normal stresses. In section 3 we will discuss a
variety of devices for measuring material properties, a process known as
rheometry. |
