Thermal Processes (FSI-DTP)

Academic year 2023/2024
Supervisor: doc. Ing. Marek Baláš, Ph.D.  
Supervising institute: EÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
Learning outcomes of the course unit The aim of the course is to teach students how to apply knowledge of thermomechanics, especially heat transfer, to practice. During their studies they will learn the theory and apparatus for heating and cooling of media. Upon successful completion of this course, students will be acquainted with all aspects of thermal, strength and hydraulic (aerodynamic) design of heat exchangers.
Learning outcomes and competences:
Students will gain advanced knowledge of solving engineering tasks in the area of heat sharing, heating and cooling. Students will acquire the knowledge needed to identify the problem and propose an optimal solution. They will acquire practical knowledge of heat exchanger designs, evaporators, dryers and similar apparatuses. Students will acquire skills in heat design of heat exchangers, calculation of pressure losses of heat exchangers and design of evaporators and dryers. This knowledge will be applicable in the areas of energy, heating, heating, air conditioning, heat recovery, chemical and process engineering, and can be applied in manufacturing plants, investors and operators.
Prerequisites:
Thermomechanics
Course contents:
The content of the course is a brief summary of basic prerequisites, overview of types of heat exchangers and their use, basic thermohydraulic design of bundle heat exchanger (tube geometry, baffles, analysis of jacket currents, calculation of pressure losses), influence of heat exchangers operation heat exchangers. The main attention will be focused on processes without phase change, but phase change exchangers (capacitors) will also be paid attention. Last but not least, the students will be acquainted with the evaporation, drying and cooling processes and with the basic design of downstream equipment.
Teaching methods and criteria:
The course is taught in the form of lectures, where students will be acquainted with specific issues of heat exchangers, evaporation, drying and other topics. The exercise is focused on practical mastery of the subject matter covered in lectures in the form of calculations and laboratory exercises.
Assesment methods and criteria linked to learning outcomes:
Assesment methods and criteria linked to learning outcomes: Course-unit credit is awarded on condition of having attended the seminars, worked out the semester work and mastered the credit example. The exam is written with possible oral correction and will verify knowledge in the field of theoretical preparation.
Controlled participation in lessons:
Controlled participation in lessons: Exercises are compulsory. The student will be compensated for absence by agreement with the tutor. Lectures are optional.
