ENG2023 : Thermal Engineering

  • Offered for Year: 2021/22
  • Module Leader(s): Professor Nilanjan Chakraborty
  • Lecturer: Dr Immanuvel Paul
  • Owning School: Engineering
  • Teaching Location: Newcastle City Campus
Semester 2 Credit Value: 10
ECTS Credits: 5.0


The aim is to provide an extension of core knowledge and skills in this field of engineering science, with applications of heat transfer and second-law of thermodynamics analysis for students who have studied this topic at university level for at least one year previously, covering different modes of heat transfer, second-law and exergy analysis.

Outline Of Syllabus

Heat transfer
•       Basic principles of heat transfer and zeroth law of thermodynamics
•       Conduction heat transfer: derivation of general heat conduction equation in Cartesian and cylindrical coordinates and their applications to steady 1D problems with and without volumetric heat generation, resistance analogy, concept of critical radius for insulation, discussion of transient 1D problems and lumped parameter analysis, conduction from extended surfaces
•       Radiation in non-participating medium: basic radiation concepts and discussion on electromagnetic waves; radiation intensity, radiation power, 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 non-dimensional 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 and h-s charts: simple steam and gas turbine cycles (Rankine and Brayton), refrigeration cycles, air-standard cycles.
•       Turbines, compressors and isentropic efficiency
•       Concepts of lost work and availability
•       Computer-aided thermodynamic analyses for power-generation cycles

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.
- Use of software in the assignment allows the students to investigate more complex (and thus realistic) problems than would be practical by hand calculation.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The end of year examination provides an appropriate way to assess both theoretical understanding and practical problem solving skills under time-constraint as required in industry.
The projects use software to allow more realistic and complex problems to be analysed.
