Intended learning outcomes
To give an understanding of how the heat transfer takes place, be able to analyse a real heat transfer problem, identify, explain and compare different heat transfer phenomena and discuss heat transports in general. It implies that the student can apply theory from the course to analyse real heat transfer problems.
After the course, the students should be able to:
Identify, formulate, model and solve problems for different heat transfer mechanisms, as well as design devices with heat exchange.
The course is given during fall semester, 2nd quarter. The course includes lectures (32 h), exercises (32 h) and four laboratory sessions and three quizzes and an examination. The lectures present the general ideas and theoretical explanations behind heat transfer. In the exercises the theory is applied for different heat transfer problems.

Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
- LAB2 - Laboratory work, 0.5 credits, grading scale: P, F
- TEN2 - Written exam, 5.5 credits, grading scale: A, B, C, D, E, FX, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Examination consists of five comprehensive arithmetical problems. During the course, three quizzes that give bonus points on the examination are given. Bonus points received for quizzes during one academic year are valid throughout that academic year (regular and re-examination).
Language of instruction: Swedish and English
Exercises: English or Swedish (depending on the assigned teacher)
Reading list: English
Lab exercise instructions and lab exercises: English
Quizzes and written examination: English
Other requirements for final grade
A written examination (TEN1; 5.5 credits) with arithmetical problems. For final mark, passed Labs are required (LAB1; 0.5 credits). Three quizzes are organised, whose result may be included at examination. Passed quizzes give bonus points on examination.
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
