Supervisor: | Ing. Jiří Hejčík, Ph.D. | |||
Supervising institute: | EÚ | |||
Teaching language: | Czech | |||
Aims of the course unit: | ||||
The course objective is to provide students with information on principles of design, and operation of heat exchanges of different types and make. | ||||
Learning outcomes and competences: | ||||
Types of heat exchanges. Principles and method of their design. Practical knowledge on how to calculate and design heat exchanger. | ||||
Prerequisites: | ||||
Fundamentals of fluid mechanics (laminar and turbulent flow) in channels and tube bundles and fundamental mechanisms of heat transfer (conduction, convection, radiation). | ||||
Course contents: | ||||
The course is concerned with the following topics: Classification of heat exchangers (HE). Basic relationships for heat transfer in HE. Efficiency of finned surfaces. Methods of heat transfer enhancement. Methods of HE calculations - LMTD and epsilon-NTU methods. Pumping power and pressure drop in HE. Correlations for heat transfer in single-phase HE. Fouling and corrosion. |
||||
Teaching methods and criteria: | ||||
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. | ||||
Assesment methods and criteria linked to learning outcomes: | ||||
Credit condition: active participation in seminars. The exam is awarded on the basis of elaboration and defense of a semester project. |
||||
Controlled participation in lessons: | ||||
Participation in classes is required and checked by the teacher. Absence can be compensated for via additional computational tasks. |
||||
