AIMS

This subject concerns the fundamental science of fluid flow relevant to a range of engineering applications, and is essential for specialisations relating to Chemical, and Civil Engineering.

INDICATIVE CONTENT

Topics covered include - Fluid statics, manometry, derivation of the continuity equation, mechanical energy balance, friction losses in a straight pipe, Newton’s law of viscosity, Fanning friction factor, treatment of roughness, valves and fittings; simple network problems; principles of open channel flow; compressible flow, propagation of pressure wave, isothermal and adiabatic flow equations in a pipe, choked flow. Pumps – pump characteristics, centrifugal pumps, derivation of theoretical head, head losses leading to the actual pump head curve, calculating system head, determining the operating point of a pumping system, throttling for flow control, cavitation and NPSH, affinity laws and pump scale-up, introduction to positive displacement pumps; stirred tanks- radial, axial and tangential flow, type of agitators, vortex elimination, the standard tank configuration, power number and power curve, dynamic and geometric similarity in scale-up; Newtonian and non-Newtonian fluids, Multi-dimensional fluid flow-momentum flux, development of multi-dimensional equations of continuity and for momentum transfer, Navier-Stokes equations, application to tube flow, Couette flow, Stokes flow.

LEARNING AND TEACHING METHODS

The subject will be delivered through a combination of lectures and tutorials. Students will also complete one experiment and one assignment which will reinforce the material covered in lectures.

INDICATIVE KEY LEARNING RESOURCES

Students will have access to lecture notes and lecture slides. The subject LMS site also contains worked solutions for all the tutorial assignments.

CAREERS / INDUSTRY LINKS

When available, presentations in a Careers Program or Professional Engineers association will be arranged.
