Specification

Pre and co requisites

Fluids and Powder Dynamics

Aims

The aim of the course is to build on the knowledge and skills learned in the fluids and powder dynamics course in year two and acquire knowledge on more advanced theories of fluids in motion, with the view to be able to solve complex fluid problems and pursue a career in the field of fluid dynamics.

Learning outcomes

On successful completion of this course a student will be able to:

1 Recognise and classify different types of fluid flows

2 Analyse fluid behaviour in specialised applications and identify appropriate governing equation for their solution

3 Apply advanced mathematical tools to solve fluid mechanics problems and recognise limitations of such tools

4 Design experimental programme for the investigation of specific fluid problems and critically appraise obtained data against expected results.

Inertial pressure, pressure transient, velocity and magnitude of pressure waves, reflection wave, slow, rapid and instantaneous closure of valves, pressure-time relationship, effect of friction, effect of pipe elasticity and hoop stresses, surge control.

Teaching and learning activity

The delivery of this course is achieved through a combination of formal lectures and tutorial session. This is complemented by a laboratory programme to re-enforce the theoretical concepts and gain hands-on experience, for example, how to set an experimental programme for the testing of fluid systems. A typical example includes the setting up of cavitation free operating envelop for pumps. To apply theories into practice, students will work on practical challenges such as the design of pipelines for slurry conveying and the design and sizing of separators for the de-watering of slurries. Tutorial sessions will be used to enhance students’ knowledge of analytical tools and their use in the solution of fluid problems.
