Class Transfer Phenomena

This Course Unit aims to understand concepts associated with heat and mass transfer, in single and multiphase systems. The student is introduced to the mathematical formulation of the topics covered, focusing on areas associated with unit operations in Engineering. In this sense, from its application and interpretation, the student will be able to design systems and equipment used for heat and mass transfer, from classic industrial production processes to biomedical devices. The relevance of this Course Unit is also completed with the study and modeling of biomedical applications such as cryobiology (in terms of biopreservation and cryosurgery) and hyperthermic biology (thermal therapy).

In theoretical classes, the contents of the program are presented, using presentations and simulations, stimulating discussion between students and teacher. In theoretical-practical classes, students solve exercises with a progressive transition of complexity.

Assessment can be continuous or non-continuous.

Continuous assessment comprises a written test (theoretical component, TC) and delivery of two exercises solved during the semester (theoretical-practical component, TPC). TC consists of two frequencies or one exam. TCP consists of delivering two exercises solved via Moodle. The final grade for the Curricular Unit results from the calculation: Final Grade = 70% TC + 30% TCP, where TC and TCP are respectively the averages of the tests given in the scope of each component.

Alternatively, at the beginning of the semester, the student can select the non-continuous assessment mode. Thus, the student is submitted to an exam, which must have a minimum grade of 9.5 for approval.
