MAS3803 : Advanced Fluid Dynamics

Semester 1 Credit Value: 10
ECTS Credits: 5.0


To present advanced topics of fluid dynamics building on the introductory concepts developed in MAS2803.

Module Summary
To introduce the mathematical tools to model two-dimensional inviscid flows more advanced than seen in MAS2803 and to predict the motion of realistic viscous flows using the Navier-Stokes equation. To illustrate the variety of solutions of the Navier-Stokes equation in the physical world, paying attention to topics such as transitions of flow patterns, and including applications to flying, weather and climate.

Outline Of Syllabus

Review of elementary fluid dynamics presented in MAS2803 (e.g. continuity equation, Euler equation, vorticity, stream function, complex potential for two-dimensional flows). More advanced
complex complex potential methods to include singularities (sources, vortices), boundaries (method of images, Milne-Thomson theorem), Magnus force (lift) and Hamiltonians. Microscopic and macroscopic description of viscosity. The Navier-Stokes equation. No-slip boundary conditions. Analytic solutions of the Navier-Stokes equation (e.g. channel flows in Cartesian and cylindrical geometries, Couette flows, oscillating flows). Transitions to complex vortex flows (flows past
cylinder, Taylor-Couette, Rayleigh-Benard and Reynolds problems). Dimensionless variables, Reynolds number, introduction to turbulence, drag. Flows in rotating frames: Coriolis, centrifugal and Poincare forces. Simple applications to weather and climate.

Teaching Rationale And Relationship

Lectures are used for the delivery of theory and explanation of methods, illustrated with examples, and for giving general feedback on marked work. Problem Classes are used to help develop the students’ abilities at applying the theory to solving problems. Tutorials are used to identify and resolve specific queries raised by students and to allow students to receive individual feedback on marked work. In addition, office hours (two per week) will provide an opportunity for more direct contact between individual students and the lecturer.

Assessment Methods

Assessment Rationale And Relationship

A substantial formal unseen examination is appropriate for the assessment of the material in this module. The written exercises are expected to consist of two assignments of equal weight: the exact nature of assessment will be explained at the start of the module. The coursework assignments and the (in class) coursework test allow the students to develop their problem solving techniques, to practise the methods learnt in the module, to assess their progress and to receive feedback; these are thus formative as well as summative assessments.
