Timing and Structure
Lent term. Conduction and radiation (Prof A Boies), convection and mass transfer (Prof. S Hochgreb); 16 lectures total.
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 principles of conduction, radiation and convection and apply them to the design and analysis of engineering systems and problems
