Sustainable Development Goals
Learning Goals
The student will deepen his/her knowledge on Heat Transfer, namely, on radiative heat transfer. He/she should be able to understand the physical phenomena involved on radiative heat transfer in participating media and its interaction with the other modes of heat transfer (conduction and convection). The sudent should be able to predict raditive heat transfer, as well as radiative properties of molecular gases, particulated media and semitransparent media. A special attention to computational models to predict radiative heat transfer will be given.
Contents
1.Revisions radiation and heat transfer (solid surf)

Teaching Methods
Teaching is based on theoretical and theoretical/practical classes. The learning process should be active and should stimulate students to research and learn more about the topics discussed in the classroom. Since the number of students in the classroom is not too high, the teacher will look at each student as an individual. Each student will do some research on a topic not presented by the teacher and presented in classroom.
