Description

Heat Transfer is an advanced course which adopts a rigorous mathematical approach to the formulation and analysis of complex engineering problems in conduction, convection and radiation heat transfer. Students will be given an introduction to the Navier-Stokes, Continuity and Energy Equations, with emphasis placed on identifying the physical principles involved and the using relevant simplifications to find engineering solutions. Both analytic and computer-based solutions are explored. These studies are supplemented by a piece of coursework on the use of a computational software to solve a typical engineering problem, plus a wide range of worked examples, and problem sheets.

Intended learning outcomes

By the end of the course, students should be able to:

  • Correctly identify the physics behind a particular heat transfer problem, and explain relevant assumptions which can be applied to simply a given problem.
  • Solve the simplified equations for a range of one and two dimensional problems in conduction/convection heat transfer, including:

o Conduction in Cartesian, cylindrical or spherical coordinates with a range of boundary conditions

o Heat transfer from extended surfaces (fins)

o Convection in laminar flows over flat plates

o Convection in laminar flows through ducts or pipes

o Convection in high speed or turbulent flows

o Simplify and solve equations for thermal radiation.

Teaching details

There are 2 hours of lectures per week over 11 weeks, a 2 hour written examination at the end of the year, and a piece of coursework which students are advised to spend no more than 10 hours working on.

  • A substantial hand-out of printed notes is provided, covering all the topics in the course
  • Solutions to worked examples are done in class and made available on Blackboard
  • Worked solutions to past examination papers are provided for self-study
  • MATLAB and Excel simulations of numerical heat transfer problems are provided

A feedback session is held after submission of coursework to clarify common errors and highlight good practice.

Assessment Details

2 hour written examination (90%)

Coursework involving use of computational software (10%)
