MATH3072 Biological Fluid Dynamics

Module Overview

First, a derivation of the governing Navier-Stokes equations will be carried out in general, during which the appropriate constitutive law for a Newtonian fluid will be introduced in terms of the stress tensor. Having derived the governing Navier-Stokes equations for a viscous fluid, the relevant boundary conditions will then be discussed, before moving on to consider the equations in non-dimensional form. At this point the Reynolds number, which characterises the relative importance of inertia versus viscosity in a given flow, will be introduced. In general, the Navier-Stokes equations are difficult to solve, however, in a certain simple situations exact solutions do exist and we shall examine a number of these solutions in a variety of biological, engineering and physical examples.
