After successful completion of the course, students are able to solve simple problems of basic processes of energy transport by heat transfer. These processes are: Free and forced convection, radiation and phase change.
Introduction (problems of heat transfer); forced convection; natural convection; Phase transitions (solidification, condensation); radiative heat exchange between walls; fundamental equations of heat transfer (in moving and radiating fluids); methods of solution (survey).
The material is presented in the lecture part in face-to-face classes and examples are calculated and discussed in the exercise part. Lectures and exercises are streamed and recorded with Lecture Tube
The assessment is based on
The homework is given in TUWEL and must be uploaded to TUWEL as a .pdf file. The tests are carried out as online tests according to the usual rules. The working time is 60 minutes + 10 minutes for uploading (pdf file) in TUWEL. 15 points are awarded for each test and 10 points for each homework assignment. The maximum point that can be achieved is therefore 75 points. At least 22 points on the tests and 13 points on the homework must be achieved to pass the VU. A follow-up test will be offered in February 2023 on the entire material, which will replace the test with the lower number of points achieved. Grading scale: Sufficient from 35 points, Satisfactory from 45 points, Good from 55 points, Very good from 65 points. At the final meeting, the tests are discussed with each student and additional questions are asked. A positive final interview is a prerequisite for a positive assessment of the LVA. The test dates and access data will be announced in TUWEL.
Die Anmeldung zur Lehrveranstaltung ist nötig, damit Sie Zugriff auf die Unterlagen haben.
Für die Teilnahme an den Tests ist eine Anmeldung zur Lehrveranstalung und die Anmeldung zu einer Testgruppe (Gruppen) notwendig. Sei erhalten eine Beurteilung der Lehrveranstaltung, wenn Sie mindestens einen Test oder eine Hausübung abgegeben haben. Eine Abmeldung von den Testgruppen nach Abgabe eines Tests oder einer Hausübung ist nicht mehr möglich.

Prior knowledge of fluid mechanics is required. Mathematics previous knowledge of differential and integral
calculus as well as knowledge of simple numerical solution methods for ordinary differential equations are
desirable.
