Module information on this degree can be found below, separated by year of study.
The module information below applies for the current academic year. The academic year runs from August to July; the 'current year' switches over at the end of July.
Students select optional courses subject to rules specified in the Mechanical Engineering Student Handbook, for example at most three Design and Business courses. Please note that numbers are limited on some optional courses and selection criteria will apply.
Fluid Mechanics 2
Module aims
The ME2 Fluid Mechanics module aims to continue the development of key aspects of engineering fluid mechanics.
Topics include dimensional analysis, the mass-conservation and momentum-balance principles applied to a fluid particle, the differential form of the governing equations (Navier-Stokes), incompressible flows, exact (Couette-Poiseuille flows) and approximate (boundary layers, Blasius solution, lubrication) solutions, turbulent channel/pipe flows and the time-averaged governing equations (RANS), compressible flows (speed of sound, Mach cone, isentropic-flow relations and converging-diverging nozzles).
ECTS units: 5
Learning outcomes
On completion of this module students should be able to:
1. Explain, in terms of dimensionless groups, the requirements for complete and incomplete similarity between model (e.g. wind tunnel) and prototype flows
2. Explain the origins and nature of lift and drag relevant to aero- and hydro-dynamic design of transport vehicles
3. Solve fluid mechanics problems using the force-momentum equation in integral and differential forms
4. Derive — using an Eulerian control volume — the equations of continuity for special cases (e.g. boundary layer flow) in both Cartesian and cylindrical polar coordinates
5. Solve fluid mechanics problems describing one-dimensional compressible flow nozzles and diffusers
Module syllabus
Dimensional analysis. Notion of a fluid particle (continuum model assumption). Kinematics of a fluid particle. The material derivative. The Navier-Stokes equations. Exact solutions (laminar Couette-Poiseuille flows). Approximate solutions (boundary layers, Blasius solution, lubrication). Introduction to turbulence (origin, time-averaged governing equations, eddy viscosity) with application to channel/pipe flows. Compressible flows: speed of sound, Mach cone, isentropic-flow relations, converging-diverging nozzles.
Pre-requisites
ME1-hFMX
Teaching methods
Students will be introduced to the main topics through lectures, supported by technology (PowerPoint, Panapto and Blackboard). Short activities (using interactive pedagogies) will occasionally be introduced in the classroom setting to reinforce learning, for example through mentimeter and the like. You will be provided with problem solving sheets and should complete these as part of your independent study. Tutorials sessions will provide small group interaction with teaching staff where you are expected to engage in discussion on specific problems.
