Aim
The aim of the course is to introduce students to the basic ways of energy propagation and the basic connections of quantitative description. Discusses the solution of constant and time-varying thermal conductivity problems. Discusses the phenomenon of heat transfer in the case of natural and forced flow without state change and the practical determination of the heat transfer coefficient. Discusses the phenomenon of source and condensation heat transfer and practical calculations. Discusses heat transfer in heat exchangers, describes logarithmic mean temperature and NTU methods for thermal engineering sizing of heat exchangers. It introduces the basic connections of heat radiation (Stefan-Boltzmann law, Wien's law, Planck's law, Kirchhoff law) and the ways of practical calculation of heat radiation between bodies. Finally, the subject also covers the methods of measuring the basic thermal material properties.

General rules
Learning outcomes are assessed on the basis of four midterm tests (two quiz assessments and two summative learning performance assessments), homework and active participation in seminars (partial performance assessment). Homework is optional, it cannot be retaken. It is not possible to retake the midterm evaluations one by one, they can be retaken together at the designated time during the retake period.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | diagnostic assessment | |
| Number: | 2 | |
| Purpose, description: | In order to complete further studies successfully within the subject, it is necessary to check the existence of necessary knowledge-type competence elements in writing (midterm tests), which takes place during the practical session of the subject. The topic is determined by the supervisor. The test may consist of theoretical questions for lexical knowledge, quiz questions for the recognition of the connections between the important concepts, or essay questions on synthesizing skills and computational tasks on problem recognition-solving skills; the available working time is a minimum of 10 and a maximum of 25 minutes. | |
| Mid-term assessment No. 2 | ||
| Type: | summative assessment | |
| Number: | 2 | |
| Purpose, description: | The complex, written way of evaluating the competence elements of the subject and knowledge, ability type in the form of a midterm test. The test basically focuses on the application of the acquired knowledge, so it concentrates on problem recognition and solution. The topics covered in the midterm test are determined by the lecturer of the subject in agreement with the supervisors, the available working time is 90 minutes. | |
Detailed description of assessments performed during the examination period
The subject does not include assessment during the examination period.
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 20 % |
| Mid-term assessment No. 2 | 80 % |
The weight of partial exams in grade
There is no exam belongs to the subject.
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |
| very good (5) | Very Good [B] | 85 % - 90 % |
| good (4) | Good [C] | 75 % - 85 % |
| satisfactory (3) | Satisfactory [D] | 65 % - 75 % |
| sufficient (2) | Pass [E] | 50 % - 65 % |
| insufficient (1) | Fail [F] | below 50 % |
The lower limit specified for each grade already belongs to that grade.
Attendance and participation requirements
The lack of the value means that there is no attendance requirement.
At least 70% the exercises (rounded down) must be actively attended.
Special rules for improving, retaken and replacement
The special rules for improving, retaken and replacement shall be interpreted and applied in conjunction with the general rules of the CoS (TVSZ).
| Need mid-term assessment to invidually complete? | ||
| NO | ||
| The way of retaking or improving a summary assessment for the first time: | ||
| the summative assessments can be retaken or improved only combined | ||
| Is the retaking-improving of a summary assessment allowed, and if so, than which form: | ||
| one single, combined retake or grade-improving exam is possible for all assesments | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| out of multiple results, the best one is to be taken into account | ||
