#### Aims

- To introduce a mathematical description of fluid flow and other continuous media to familiarise students with the successful applications of mathematics in this area.
- to prepare students for future study of advanced topics.

#### Content

- Kinematic description of fluid flows: streamlines and trajectories, mass conservation and continuity equation
- Review of tensors, stress and rate of strain.
- Dynamical models of fluid flows: Euler and Navier-Stokes equation.
- Some methods to solve Euler and Navier-Stokes equations.
- Waves: sound and water waves, linear and nonlinear.
- Topics from: thermodynamics, scaling and dimensional analysis, hydrodynamic stability, NSE and turbulence, non-Newtonian fluid flows.
- Reading material on a topic related to: hydrodynamic stability, turbulence.

#### Learning Outcomes

Subject-specific Knowledge:

- By the end of the module students will: be able to solve complex, unpredictable and specialised problems in Continuum Mechanics.
- have an understanding of specialised and complex theoretical mathematics in the field of Continuum Mechanics.
- have mastered a coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas: Kinematics of fluid flows.
- Equations of motion and their derivation for fluids.
- have an advanced understanding in one of the following areas: hydrodynamic stability, turbulence.

Subject-specific Skills:

- In addition students will have highly specialised and advanced mathematical skills in the following areas: Modelling.
- They will be able to formulate and use mathematical models in various situations.

Key Skills:

- Students will be able to study independently to further their knowledge of an advanced topic.

#### 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.
- 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 high level of rigour as well as feedback for the students and the lecturer on students' progress.
- The end-of-year examination assesses the knowledge acquired and the ability to solve complex and specialised problems.
