Aims

The aim of the Module is to build on the knowledge and skills learned in the fluids and powder dynamics Module 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 module a student will be able to:
1 Acquire an in-depth knowledge of theories relevant to Fluid problems.
2 Analyse fluid behaviour in specialised applications and use of different measurement tools.
3 Apply advanced mathematical tools to solve typical fluid mechanics problems.
4 Design analyse systems for the conveying of fluids and slurries.

Indicative content

Design & sizing pipelines for slurry conveying
Non-Newtonian fluids, Hydraulic conveying, head losses in slurry pipelines, pumps and slurry pumping

Selection of pumps for specific duties
Characteristics of rotodynamic and positive displacement pumps, net positive suction head required and available, cavitation in pumps, pump scaling

Selection of journal and thrust pad bearings
Introduction to lubrication, pressure distribution in bearings, application of laminar flow to bearings

Compressible flows and calculation of supersonic nozzles
Thermodynamic laws and concepts, energy equation, total pressure and total temperature, speed of sound, Mach number, Mach cone, shock waves and flow discontinuity, pitot static tube for high speed flows, one dimensional isentropic flow in ducts, De Laval nozzle, effect of compressibility on drag

Compressible flow in pipes
Constant density model, isothermal flow at low to moderate velocities, isothermal flow model at high velocities

Design & sizing of flow measuring instruments
Level measurement, pressure measurement, velocity measurement, flow rate measurement

Transient flow in pipes
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 Module 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.

Nature of FORMATIVE assessment supporting student learning:
A series of tutorial sessions will be organised in class to solve practical problems collectively and give feedback to students on their pre-class attempts. Mock exams will also be organised to test students understanding of the subject and familiarise with typical exam questions and exam conditions. Collective feedback will be given on the mock exam.
