AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide knowledge of heat transfer equipment, such as the classic tube heat exchangers, plate exchangers, Compact Heat Exchangers; than students study the direct contact heat exchangers, such as evaporative cooling and condensers; finally the course analyzes the thermal design of recuperators and their proper use in plants.

AIMS AND LEARNING OUTCOMES

At the end of the module the students will have acquired the skills for selecting, sizing and evaluate the performance of many heat exchanger categories present in industrial and civil installations.

In addition to theoretical knowledge of analysis and modelling, the students will have acquired a technical qualification enabling them in designing heat exchanger systems and in the optimization of the performance.

Teaching methods

The course consists of lectures and practical applications.
