Aims
The aim is to provide an extension of core knowledge and skills in this field of engineering science, with applications of heat transfer, second-law of thermodynamics and exergy analysis for Stage 2 Mechanical Engineering students.
Outline Of Syllabus
Introduction to the basic principles of heat transfer and zeroth law of thermodynamics
Conduction heat transfer: governing equations, steady state and transient heat conduction problems and heat conduction from extended surfaces
Radiation in non-participating medium: basic radiation concepts and discussion on electromagnetic waves; Planck’s distribution, Stefan-Boltzmann law, Wein’s law, concept of black body, concepts of emissivity, absorptivity and transmissivity, concepts of view factor, radiation exchange between surfaces
Convective heat transfer: concept of thermal boundary layer, concepts of forced convection for external flows, forced convection in ducts, natural convection, heat transfer correlations and nondimensional numbers, dimensional analysis of convective transfer problems involving Buckingham’s pi theorem.
Heat exchanger analysis: Introduction to different types of heat exchangers, concepts of overall heat transfer coefficient, log-mean temperature difference (LMTD) analysis, effectiveness of heat exchangers, e-NTU analysis
Second law of thermodynamics, Kelvin-Planck and Clausius statements; Carnot cycle, concept and origin of irreversible processes, Clausius inequality; Concept of entropy, TdS relationships,
Second-law analysis of cyclic processes: process and cycle representation on T-s charts; isentropic efficiency, concepts of lost work, irreversibility and exergy.

| Guided Independent Study | Assessment preparation and completion | 26 | 0:30 | 13:00 | Recommended revision for exams, assuming prior regular independent study throughout the teaching |
| Guided Independent Study | Assessment preparation and completion | 1 | 3:00 | 3:00 | NUMBAS examination |
| Scheduled Learning And Teaching Activities | Small group teaching | 11 | 1:00 | 11:00 | Tutorials |
| Guided Independent Study | Independent study | 1 | 33:00 | 33:00 | Includes background reading and reading lecture notes for a full understanding of the material. |
| Total | 100:00 |
Teaching Rationale And Relationship
- Lectures convey the underlying engineering sciences and the approaches required to apply these to the discipline-specific problems identified.
- Tutorials support the students' self-study in reading around the lecture material and learning to solve the practical engineering problems posed by the Tutorial Questions.
Assessment Methods
The format of resits will be determined by the Board of Examiners
Exams
| Description | Length | Semester | When Set | Percentage | Comment |
|---|---|---|---|---|---|
| Digital Examination | 180 | 2 | A | 100 | Open book, open notes examination using NUMBAS |
Assessment Rationale And Relationship
The end of semester examination will provide an appropriate way to assess both theoretical understanding and practical problem-solving skills under time-constraint as required in industry. The open book and open notes examinations allow for the evaluation of conceptual understanding rather than memorising materials which are available in engineering handbooks. All the skills outcomes are assessed in the questions asked in the examinations. One 3-hr long exam ensure that all the learning outcomes are properly assessed without any alternative choices and within a reasonable timeframe. The summative feedback from the mid-semester exam also helps the students to perform better in the end of semester examination. The timetabled tutorials will be used for formative assessments of the students and thus it is not explicitly stated under teaching activities.
