What will I learn on this module?

This module is designed to introduce fundamental concepts in the mathematical area of Fluid Dynamics. You will analyse the equations of continuity and momentum, and will investigate key concepts in this area. We will introduce the Navier-Stokes equations, and case studies will be used to visualise and analyse real-world problems (using appropriate software) as appropriate to delivery of the module. Initially, we will use the inviscid approximation and then utilise analytical and computational techniques to investigate flows. The second half of the module is a specialist course in laminar incompressible viscous flows, encompassing background mathematical theory allied to a case study approach, with solution to problems by both analytical and computational means.

Assessment of the module is by one individual assignment (30%) and one formal examination (70%).

The module is designed to provide you with a useful preparation for employment in an applied mathematical environment or engineering environment.

Outline Syllabus
• Introduction of fluid dynamics, Navier-Stokes equations, equations of continuity and momentum for inviscid flow, unsteady one-dimensional flow along a pipe, irrotational flow, Bernouilli's equation, stream function formulation, flow past a cylinder, velocity potential.

• Low Reynolds Number Flow including: (i) lubrication theory, slider bearing, cylinder-plane, journal bearing, Reynolds equation, short bearing approximation; (ii) Flow in a corner, stream function formulation, solution of the biharmonic equation by separation of variables.

• High Reynolds Number Flow including boundary layer equations, skin friction, displacement and momentum thickness, similarity solutions, momentum integral equation, approximate solutions.

How will I learn on this module?

A wide range of learning and teaching approaches are used in this module. The module will be delivered using a combination of lectures and seminars in which students will be able to obtain help with problems associated with the module. Where deemed appropriate, computer laboratory sessions will be utilised to complement the taught material. Lectures allow students to experience and understand the formalism of the relevant mathematical techniques and include relevant examples. Seminars allow students to work through problems to develop their knowledge and skills, with the support of the tutor. Consequently, students have an opportunity to enhance their understanding of the subject through seminars which promote independent learning and tackle relevant problems. The mathematical rigour associated with this module naturally increases students’ employability and is a highly transferrable skill.

Students will be assessed by coursework (30%) and a formal examination (70%). The examination will cover all topics from the module. Written feedback will be provided on the coursework. Exam feedback will provided individually and also generically to indicate where the cohort has a strong or a weaker answer to examination questions.

How will I be supported academically on this module?

In addition to direct contact with the module team during lectures and seminars, students are encouraged to develop their curiosity by making direct contact with the module team either via email or the open door policy operated throughout the programme. Students will also be regularly referred to supporting resources including relevant texts and relevant multimedia materials.

References to these resources will be made available through the e-learning portal and in lectures and seminars.

Module abstract

This module is designed to introduce fundamental concepts in Fluid Dynamics - an important topic in Applied Mathematics – using both analytical and computational techniques. We will introduce the Navier-Stokes equations and case studies will be used to visualise and analyse real-world problems (using appropriate software) as appropriate to delivery of the module. The second half of the module is a specialist course in laminar incompressible viscous flows, specifically considering high and low Reynolds number flows, and encompassing background mathematical theory allied to a case study approach, with solution to problems by both analytical and computational means. Assessment of the module is by one individual assignment (30%) and one formal examination (70%). The module is designed to provide students with a useful preparation for employment or postgraduate study in an applied mathematical or engineering environment.
