Thermodynamics (3 cr)

Evaluation scale

H-5

Content scheduling

The course takes place in weeks 36-50.

The course introduces thermodynamic phenomena and practices related calculations and measurements from a physics perspective. The first hours of the week are theory lessons on the topic of the week. At the same time, we review any unclear points from the previous week's calculations. The second lesson is a calculation workshop (1 hour).

(In addition to the theory lessons, the course includes one mandatory lab assignment in small groups. The lab assignments are divided into two topics: Thermal conductivity of the thermistor or calorimetry. The assignments are peer-reviewed.)

Contents
- Basic quantities of thermophysics/thermodynamics, formulas, units, pressure, buoyancy
- Thermodynamic system, temperature and thermal expansion
- Heat capacity, thermal energy and energy transfer
- Changes in state and energy in changes in state
- Flows of liquids and gases, flow equations
- Viscosity of a liquid
- Equation of state of an ideal gas
- First and second law of thermodynamics
- Introduction to gas cycle processes
- Introduction to the operating principles of heat and refrigeration machines

Objective

The aim of the course is to familiarize students with the fundamentals of heat transfer and thermodynamics, thereby creating a basis for their application in the design and calculation of machines, equipment, and processes.
After completing the course, student:
- is familiar with the basic quantities of thermodynamics and can perform related calculations
- understands heat transfer and its effects in substances and structures (heat conduction , thermal expansion, phase changes)
- can calculate the heat quantity in various state changes
- can perform calculations related to the flow of liquids and gases
- knows the ideal gas equation and can apply it in various state change processes
- understands the state changes of ideal gases and the cycles based on them
- can determine the thermal efficiency of a heat engine as well as the coefficients of performance of a heat pump and a refrigeration machine
- can evaluate the energy efficiency of different machines
- is familiar with the Mollier diagram and its use in calculations related to heat transfer processes
- can investigate thermodynamic phenomena using measurement setups

Teaching methods

Participatory learning, teacher-led teaching

Exam schedules

The dates of the 2 midterm exams will be announced at the start of the courses.
Retake opportunities for the general EY Technology retake exams in December and January.

Pedagogic approaches and sustainable development

Methods based on the student's own activity, experience and knowledge building. The course's core content is understanding energy flows and sustainable solutions in energy technology.

Completion alternatives

Proof of competence through a theory test. This option must be agreed with the teacher. If you have studied a course of a similar level and content, it is possible to pass the course. Ask the teacher for instructions on this.

Student workload

The student's workload of 81h is divided as follows
- Theory classes and calculation exercises 22h
(- Familiarization with laboratory work and working in the laboratory 2h)
- Exam review 3h and Exam 2h
- Independent study 54h

Evaluation methods and criteria

The course is assessed numerically on a scale of 0-5 based on the exam(s) (max 100 points). If the student completes the course with midterm exams, both exams must be taken. If the student fails the second midterm exam, the course will be taken with an exam either on the actual exam day or in a retake.

Attendance is mandatory for theory classes, calculation classes and laboratory meetings. Absences must be reported and agreed with the teacher in advance.

Independently completed ViLLE calculation exercises can earn a maximum of 12 points (corresponding to the grade of the exam). Preliminary assignments are worth 4 points.

The lab work included in the course must be completed successfully (active work in the lab, a completed measurement protocol and participation in peer review).

Failed (0)

The student does not achieve at least 40% of the course points = 40p (or the student has not completed the mandatory lab work successfully.)

Assessment criteria, satisfactory (1-2)

Grade 1 requires approximately 40% of course points = 40p and a successfully completed lab work.
Grade 2 requires approximately 52% of course points = 52p and a successfully completed lab work.

Grade 1-2 level competence means knowledge of basic thermodynamic phenomena and mastery of calculations related to basic thermodynamic quantities.

Assessment criteria, good (3-4)

Grade 3 requires approximately 64% of course points = 64p and a successfully completed lab work
Grade 4 requires approximately 76% of course points = 76p and a successfully completed lab work

Level 3-4 competence in grade 3-4 means, in addition to the previous level of competence, mastery of the main rules of thermodynamics and an understanding of gas processes.

Assessment criteria, excellent (5)

A grade of 5 requires approximately 88% of course points = 88 points and a successfully completed lab work.

A grade of 5 level of competence means, in addition to the competence of the previous levels, calculation skills related to flows, especially the application of Bernoulli's equation in various situations and/or the ability to describe gas processes in more detail.

Further information

The most important announcements for the course will be sent by email. Students are encouraged to contact the teacher primarily by email. You can also ask questions and discuss matters openly during classes.
Current issues are announced on the its course Overview page.
Completion of the course requires continuous physical presence at meetings.
