Course contents :
|
| The course will cover the fundamentals of heat transfer processes. In particular, following topics will be treated:
- Types of heat transfer mechanisms (conduction, convection, radiation) and their physical origin, key definitions (flux, heat, temperature...), conservation equations, relation to thermodynamics, general solution methodology
- Conduction: Fourier's law, heat diffusion equation (1D, 2D, unsteady), shape factor, analogy with electrical circuits
- Convection: velocity and thermal boundary layer, convection coefficient, Nusselt number, laminar vs. turbulent, natural vs. forced, external vs. internal
- Boiling and condensation: critical point, nucleate pool boiling, film condensation
- Heat exchangers: types (parallel, counter-flow), analysis (number of transfer units NTU, log mean temperature difference)
- Radiation: emission, irradiation, black body, gray surface, real surfaces, view factors
- Multimode heat transfers
|
|
Learning outcomes of the course :
|
| At the end of the course, students should be able to quantify the heat transfers in a large range of practical applications. This involves the following skills:
- to identify the relevant heat transfer processes in place
- to estimate the non-dimensional numbers characterizing the different heat transfer modes
- to select and apply the appropriate principles of conservation and constitutive laws
- to use the appropriate resolution method and quantify the heat transfers
- to critically assess and discuss the results
|
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
|
- Basics of thermodynamics (e.g., CHIM0286 "Elements de thermodynamique")
- Basics of mathematics (e.g., MATH0007 "Analyse mathématique II")
|
|
Planned learning activities and teaching methods :
|
| The course is based on theory sessions (~30h) and exercise sessions (~30h).
- The general concepts and their mathematical expression are exposed during the theory sessions. Theoretical results are discussed in details and illustrated using practical examples.
- During the exercise sessions, the students are invited to apply the techniques introduced during the theory sessions in order to solve practical problems. The exercise sessions also include 1 or 2 experimental laboratories (to be confirmed).
|
|
Mode of delivery (face-to-face ; distance-learning) :
|
| Face-to-face learning (4 hours a week during the second quadrimester) |
