| Core: | Optional: |
|
|
|
Aims
To provide a knowledge of heat transfer that is of vital importance in many industrial sectors from process industries, through vehicles, etc., power plant, to building technology.
Learning Outcomes
By the end of the module the student should be able to...
- Understand the basic heat transfer processes.
- Calculate heat transfer rates using correlations of non-dimensional groups, analytical techniques or numerical techniques.
- Model real-life processes for the purposes of approximate calculation.
- Understand the compromises between effectiveness and cost inherent in the design optimisation of heat transfer equipment.
Syllabus
The theoretical background to heat and mass transfer by conduction, convection, radiation, condensation and boiling is given. The design applications developed concentrate on more realistic mixed mode or complex heat transfer, e.g. fins (heat sinks for electronic components, compact heat exchangers), flat plate solar collectors, heat exchangers, etc. The assessed portion of the course will be a heat exchanger design optimisation exercise.
Introduction: Problems in heat transfer. Heat exchangers. U-Values and pressure drops
Conduction revision: 2- and 3- D conduction with generation. 1- and 2- D unsteady conduction.
Convection: Continuity, momentum, energy equations as applied to boundary layers. Laminar and turbulent flow. Dimensional analysis. Forced convection heat transfer and pressure drops: in tubes, across tube banks, on flat plates. Natural convection.
Condensation and boiling.
Radiation heat transfer.
Heat exchanger types.
Applications: Mixed conduction and convection - fin effectiveness. Mixed radiation and convection - flat plate solar collector. Heat pipes. Building heat transfer.
LMTD and E-NTU design methods.
Heat exchanger design optimisation.
CAD methods in heat transfer design.
