Type Description Codes of the learning outcomes of the module to which assessment is related
exam [MB_35_w_1]
The global assessment of the learning outcomes is made with an oral exam (1h on average). The exam consists of 2-3 practical exercises to be implemented and solved by the candidate, covering the key subjects of the class (transport of species and heat, steady-state and transient solutions). Based on the exercises, the general knowledge of the meaning of dimensionless quantities, asymptotic behaviors, and correlations among different fields, will be assessed. The correct implementation of the practical exercises is a necessary criterion to succeed in the exam.
