Timing and Structure

Lent term. Conduction and radiation (Dr A. Boies), convection and mass transfer (Dr J Sidey); 16 lectures.

Aims

The aims of the course are to:

  • Provide an understanding of the fundamentals of heat and mass transfer processes in engineering systems.
  • Provide methods for analysis and solution of problems involving heat and mass transfer using fundamental differential analysis.
  • Guide the process of scaling analysis and finding solutions by analogy.

Objectives

As specific objectives, by the end of the course students should be able to:

  • Understand the different modes of heat transfer, and their physics, and apply their knowledge to design and analysis of heat transfer problems
  • Understand the principles of conduction, radiation and convection, and apply these principles to solve engineering problems
  • Understand the analogy between heat, mass and momentum transfer
  • Understand the origin and use of non-dimensional groups and their analogues in heat, mass and momentum transfer
  • Understand the principles of phase change
  • Understand the process of mass diffusion in gases, liquids, and solids
  • Develop an intuition for scaling and magnitudes in heat transfer
  • Develop an understanding of numerical and expeirmental methods for solving practical problems
