Teaching methods
This course combines lectures in class, sessions of exercises in class, exercises of simulation (computer) using Aspen +, and a laboratory
Evaluation methods
Exam (theoretical and practical questions). The exam is divided in three parts related to 1) heat exchangers, 2) pump and compressors and 3) exergy analysis. The students have to pass the three parts to credit the course.
Exercises proposed during the course could be contribute to the final mark.
Other information
This course requires basic knowledge of hydrodynamics & transport phenomena, thermodynamics and applied mathematics.
