Course detail
Heat Exchangers
FSI-LVT Acad. year: 2022/2023 Winter semester
Course contents: Summary of basic prerequisites, work with standardization of TEMA and its use in the basic design of heat exchangers, detailed design of the bundle heat exchanger (tube geometry, bulkheads, sheath current analysis), vibrations induced by flow in the shell (prediction, criteria of severity, design), calculation of pressure losses, strength calculation, influence of exchangers (corrosion, fouling) on the design of exchangers. The other principles will be the basic principles for designing phase change exchangers (capacitors, reboilers). Last but not least, the students will be introduced to the basic design of other types of exchangers – plate heat exchangers and regenerative exchangers.

Learning outcomes of the course unit
Students will acquire advanced knowledge of engineering tasks in heat exchanger designs. The student will acquire practical skills in heat design of heat exchangers, calculation of pressure losses and strength calculations. This knowledge will be used in the fields of power engineering, heating, heating, air conditioning, heat recovery, chemical and process engineering, and can be used in manufacturing plants, investors and operators.
Prerequisites
Thermomechanics, Combustion Devices and Heat Exchangers, Heat and Mass Transfer
Planned learning activities and teaching methods
The course is taught in the form of lectures, where the students will be acquainted with specific methods of calculation of exchangers. Exercise is focused on the practical handling of the substance discussed at the lectures.
Assesment methods and criteria linked to learning outcomes
The granting of credit is conditioned by activity on exercises, processing semestral work and mastering of the credit test. The exam is written with a possible oral correction and will verify the knowledge in the field of theoretical preparation.
Aims
The aim is to get acquainted with all aspects of heat, strength and hydraulic (aerodynamic) design of heat exchangers.
