| Course contents : | Performance of heat exchangers in steady-state and transient regimes. Heat exchangers logarithmic mean temperature difference (LMTD), effectiveness and number of heat transfer units. Types of heat exchangers studied: double-pipe, finned tubes, plate-fin, shell and tube, plates, fixed and rotating regenerators, serpentine and tank, heat pipes, radiant heat exchangers, heat recovery steam generator (HRSG), cooling towers, tanks for ice stocking and destocking.
Design criteria : heat duty, pressure drop, manufacturing facility, fouling and cleaning, fluids types (corrosion, temperature, pressure and possible leakages) |
|
| Course objective : | The course is aimed at giving to the students the fundamental notions needed for solving the rating and sizing (design) problems (overall heat transfer coefficient as well as the pressure drops in the two streams) of different types of heat exchangers. |
|
| Prerequisites : | Course MECA002-0 "Thermodynamique appliquée et introduction aux machines thermiques"
Course MECA019-0 "Transferts de chaleur" |
|
| Workshops : | Practical exercises are solved and homeworks are proposed. Two test benches available in the laboratory are used to train the students and a visit of an industrial plant is organised. |
|
| Organization : | The course consists in oral presentations illustrated by practical cases. It is given during the first semester. |
|
| Written notes : | The course contents is extracted from :

|
| Assessment : | A personnal work (choosen among a precirculated list of themes) has to be performed and presented to the other students. That work counts for 75% of the global mark and the reports of laboratory work for 25%. |
