Learning Outcomes
Acquire knowledge of the different heat transfer modes: conduction, convection, radiation. Acquire knowledge about heat exchangers and associated methods of calculation. Develop ability to reflect on mono dimensional problems. Develop ability to solve these problems with the help of electrical analogy (thermal networks method).

Content
The approach on theory is made in masterclasses and with class exercises on the following points: - Conduction: Fourier law, general three-dimensional heat conduction equation for steady state and unsteady conditions, introduction to the concept of thermal resistance. - Convection: Newton law, dimensionless numbers and used correlations in convective transfer situations. - Radiation: study of black bodies and gray bodies, Stefan-Boltzmann law, equivalent thermal network to treat radiation problems. - Application to insulation problems, study of combined transfers (example with fins). - Heat exchangers: description of the main types, study of associated calculation methods.
