DESCRIPTION - summary of the module content

AIMS - intentions of the module

To introduce students to the theory, principles and practice of engineering fluid mechanics, thermodynamics and heat transfer, and to prepare for advanced courses in these areas.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

Note:
List A comprises core outcomes that will be covered fully in lectures and must be achieved by all students to meet the minimum university requirement for progression.
List B comprises outcomes that are EITHER more difficult to achieve OR are to be achieved by private study (or both).
All outcomes will be assessed, and coverage of List B outcomes is essential for both BEng and MEng students.
[b]A: THRESHOLD LEVEL[/b]
(1) Fluid Dynamics: Students should be able to:
Describe basic methods of measuring pressure, velocity and speed in a fluid flow. Distinguish between laminar and turbulent flow, classify flow types using Reynolds number.
Apply control volume concept to a fluid flow.
Use conservation of mass, momentum within control volume to derive solutions to simple problems (e.g. Jet impact).
Identify terms in Bernoulli's equation, head equation, apply to internal flows including the effects of head losses in pipes and fittings: use Darcy-Weisbach equation and Moody diagram to determine head losses; solve head loss problems.
Describe fundamentals of open channel flow; distinguish between sub- and super-critical using Froude number, explain basics of flow in weirs and flumes.
Distinguish between concepts of streaklines, streamlines, pathlines: describe basic concepts of potential flow and potential/stream functions; identify when potential/stream functions applicable; compute vorticity for a given flow explain and justify concept of a boundary layer.
(2) Energy conversion and heat tranfer.
Students should be able to:
Quote the first law of thermodynamics; explain the concepts of heat and work, Internal energy, enthalpy & heat capacity; identify and differeniate between closed and open systems, steady flow; apply these concepts to perform simple work and power calculations.
Quote the second law of thermodynamics, define entropy; contrast perfect gases, real substances; use thermodynamic data from charts and steam tables, perform calculations for heat transfer, throttling, compression and expansion.
Discuss compressors and turbines, identify types, calculate flow rates, perform work and power calculations.
Analyse steam power plant, contrast variants; discuss basics of electricity generation.
Contrast basic heat transfer mechanisms; conduction, convection, radiation; select and evaluate appropriate dimensionless groups to describe heat transfer in different cases; evaluate heat transfer coefficients; classify heat exchangers (shell and tube, cross flow, etc).
[b]B: GOOD TO EXCELLENT[/b]
(1) Derive dimensionless groups from specified variables.
Use integral techniques to evaluate flow rates in non-uniform flows.
Identify minor losses and apply standard formulae to include their effect in pipe flow problems; solve flow rate and sizing problems; identify head, flow and power coefficients for pumps and match flow and power to pipes.
Evaluate hydraulic radius and calculate flow rates through open channels composed of a variety of materials using Chezy and Manning formulae; calculate flow rates over weirs (broad-crested, thin plate) using standard weir equations.
Evaluate velocity components from given potential/stream functionin cartesian and polar coordinates; derive potential/stream functions from each other and from velocity components; apply Bernoulli's theorem along a streamline to determine pressure, solve external flow problems; summarise and resolve d'Alembert's paradox.
(2) Discuss Gibbs and Helmholtz functions; apply and manipulate thermodynamic functions and relationships to solve thermodynamic system problems;
summarise thermodynamic aspects of perfect gases, contrast with real substances; perform more complicated work and power calculations.
Calculate cycle, work, heat, power, and efficiency for Carnot and Rankine cycles;
evaluate efficiencies, coefficients of performance
Perform heat exchanger design calculations; solve heating and cooling problems, coupled conduction/convection, natural convection and heat transfer with phase change problems; discuss basics of radiative heat transfer.
