Prof W N Dawes and Dr N Atkins
Timing and Structure
Lent term. Conduction and radiation (Dr N R Atkins), convection and mass transfer (Prof. W N Dawes); 16 lectures.
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.
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
- 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
