A presentation of the most elementary form of pulsatile flow as an important prerequisite for the study of other flow applications in biological systems. The book provides in a single source a complete treatment of the fluid dynamics of flow with the required mathematics and emphasis on the basis mechanics. The style and level of this book make it accessible to students and researchers in biophysics, biology, medicine, bioengineering and applied mathematics working in theoretical and clinical work on the cardiovascular system, as well as in the design of new instrumentation, medical imaging systems, and artificial organs. With problems and exercises.

We study dispersive models of fluid flow in viscoelastic vessels, derived in the study of blood flow. The unknowns in the models are the velocity of the fluid in the axial direction and the displacement of the vessel wall from rest. We prove that one such model has a well-posed initial value problem, while we argue that a related model instead has an ill-posed initial value problem; in the second case, we still prove the existence of solutions in analytic function spaces. Finally, we prove the existence of some periodic traveling waves.

The flow of a Casson fluid under periodic pressure gradient in a rigid tube, in the low-frequency limit has been examined. Results show that the quasi-steady solution, where time acts as a parameter and not as an independent variable, can be used to construct accurate solutions of such a flow, which are applicable to the flow of blood in small vessels of low shear rate. As an illustration, the flow under a sinusoidal positive pressure gradient was computed for the quasi-steady theory, and the nonlinear relation between flow and instantaneous pressure gradient was clearly shown by the blunting of the flow-rate curve, which occurs when the numerical magnitude of the pressure gradient is small.
