Organisation and examination
Teaching in the first semester, review in January
Schedule
Units courses prerequisite and corequisite
Prerequisite or corequisite units are presented within each program
Learning unit contents
Performance (heat flow rate and pressure drops) of heat exchangers in steady-state regime. Heat exchangers logarithmic mean temperature difference (LMTD), effectiveness and number of heat transfer units. Types of heat exchangers studied: double-pipe, tube-fin, plate-fin, shell and tubes, plates, fixed and rotating regenerators, serpentine and tank, heat pipes, radiant heat exchangers, heat recovery steam generator (HRSG), cooling towers (direct contact and indirect contact).
Design criteria : heat duty, pressure drop, size, manufacturing facility, fouling and cleaning, fluids types (corrosion, toxicity, temperature, pressure and possible leakages).
Learning outcomes of the learning unit
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.
Prerequisite knowledge and skills
Course MECA0002-1 "Thermodynamique appliquée et introduction aux machines thermiques" Course MECA0445-2 "Heat transfer"
Planned learning activities and teaching methods
Practical exercises are solved and mandatory homeworks are proposed. A visit of an industrial plant is organised.
Mode of delivery (face-to-face ; distance-learning)
The course consists in oral presentations illustrated by practical cases. It is given during the first semester.
A copy of the slides is sent by e-mail to the students the day before each lecture.

Assessment methods and criteria
At the end of the course, a personnal work has to be performed on a problem of design of a heat exchanger. That work counts for 50 % of the global mark and the reports of the homeworks for 50 %.
