where most of the theory and results considered in the course can be found. for further reference also the following book can be considered:

particularly focused on the different thermodynamic models available, and

to have example on the use of exergy in the analysis of thermodynamic processes.

Metodi didattici


Modalità di verifica e valutazione dell'apprendimento

The course assessment will be based on a written and an oral exam.

Only student with a score of 16/30 or higher in the written part will be admitted to the oral exam.

The written exam will request the solution of 1 or 2 exercises involving pure substances and mixtures thermodynamics. The use of personal materials and textbook is allowed, the use of laptop is permitted even if not suggested or striclty necessary.

Midterm exams will be considered depending on the schedule constraint, in case the first one will be on mid november focused on pure component thermodynamic while the second one will be soon after the course (before christmas) focused on mixture thermodynamics.

The oral exam will be based on the discussion of different topics presented during the course considering both applications and theoretical backgrounds. The oral exam will be usually based on two question and counts more (about 2/3) than the written part in determining the final grade.

Strumenti a supporto della didattica

The slide presented during the lesson as well as other supporting materials (exercise, older exam and so on) will be made available on insegnamenti online (https://iol.unibo.it/) before the beginning of the lesson and during the lesson in case of particular needs or update.
