Teaching methods
Presential classes and exercises;
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 independently to pass the course.
Other information
This course requires basic knowledge of hydrodynamics & transport phenomena, thermodynamics and applied mathematics.
