Aims
- To introduce some important ideas in modern fluid dynamics and applied mathematics through the study of fluid systems motivated by geophysical and astrophysical contexts.
- To prepare students for future research in Applied Mathematics.
Content
- Equations of geophysical fluid dynamics and common approximations.
- Dynamics of rotating fluids.
- Quasi-geostrophic theory.
- Stratified flow.
- Fluid Instabilities.
- Equations of magnetohydrodynamics (MHD), and their ideal and diffusive limits.
- MHD equilibria: potential, force-free and magnetohydrostatic solutions.
- MHD waves.
- Introduction to dynamo theory.
Learning Outcomes
Subject-specific Knowledge:
- By the end of the module, students will:
- be able to solve novel and/or complex problems in Fluid dynamics and MHD.
- have a systematic and coherent understanding of the mathematical formulation behind the geophysical and astrophysical models.
- have acquired a coherent body of knowledge of rotating and stratified fluids and MHD through study of fundamental behaviour of the models as well as specific examples.
Subject-specific Skills:
- Students will develop specialised mathematical skills in mathematical modelling which can be used with minimum guidance.
- They will be able to formulate applied mathematical models for various situations.
Key Skills:
- Students will have basic mathematical skills in the following areas: problem solving, modelling, computation.
Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module
- Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
- Problem classes show how to solve example problems in an ideal way, revealing also the thought processes behind such solutions.
- Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
- Formatively assessed assignments provide practice in the application of logic and a high level of rigour as well as feedback for the students and the lecturer on the students’ progress.
- The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
