Objectifs Généraux
Upon completion of the course, the student will be able to
1. Extend the basic knowledge acquired in the introduction to heat transfer course and relate it to more advanced/practical application.
2. Use existing solution to solve transient and multi-dimensional heat conduction problems.
3. Compute heat exchange rates in problems including natural convection and boiling/condensation heat transfer.
4. Perform an analysis of the performance and the sizing of a heat exchanger.
5. Solve problems on radiation exchange between mulitple surfaces, which is a primary quantity of interest in most radiation problem.
