Unsteady Non-Newtonian Flows through Collapsible Tubes with Special Reference to the Large Intestine

Abstract: Food that is being digested and absorbed within the gastrointestinal tract (digesta) is a non-newtonian fluid that navigates its way through otherwise collapsed conduits. The properties of viscoelasticity are important in this setting and aid movement through the intestine propelled by smooth muscle contraction. We discuss problems related to modelling such flows in the large intestine, insights obtained and the correlates with abnormal function in humans.
