## Module aims

To develop further the theoretical understanding and mathematical techniques necessary for analysing fluid flows and their biological applications.

## Module learning outcomes

• Analyse and understand different flow regimes

• Understand theories underlying fluid flow dynamics

• Be able to carry out exact and approximate calculations for important types of fluid flows

## Module content

Syllabus

• Two dimensional inviscid flows and the complex variables formalism.

• Very viscous (Stokes) flows: basic equations and boundary conditions. Reversibility.

• The Stokes drag for a sphere and its generalisations to bodies of complex shapes.

• The far-field flow approximation for bodies in very viscous flows. The Oseen tensor.

• Calculate the swimming velocity of a wavy sheet and relate this to swimming by ciliates.

• Use resistive force theory to analyse the swimming of bacteria and spermatozoa.

• Thin film flows.

Academic and graduate skills

• Academic skills: The skills taught are used in many areas of applied mathematics and mathematical physics and are essential for modern applications of fluid dynamics. Students on this module will analyse two important topics of mathematical biology in addition to the material of the H-level variant of the module.

• Graduate skills: students will develop their ability to assimilate, process and engage with new material quickly and efficiently. They will develop problem-solving skills and learn to analyse critically different approaches. Students on this module will learn to work more independently than those on the H-level variant.
