Lecturer: Dr.-Ing. Sebastian Schmitt

Workload: 4 SWS per week, 5 ECTS credits

Prerequisites: Thermodynamics I

Start: Wednesday, October 21, 2026

Exam date, winter semester 2026/27: Wednesday, March 3, 2027

All downloads and further information are provided on the e-learning platform (OLAT course). Please enroll using the course code announced in the first lecture.

Exam admission requirement: To be admitted to the exam, you must first complete a preliminary coursework requirement. Details will be announced in the lecture and tutorial.

The following aids are permitted in the exam:

• A non-programmable calculator.
• One A4 sheet, prepared by the candidate before the exam, which may be written on both sides. You can use it, for example, to note important formulas from the lecture. The sheet must be handed in together with your answers at the end of the exam. Its contents will not be graded.

We will provide the following in the exam:

• Property data and tabulated values
• Any diagrams needed to solve the problems, including definitions of the quantities shown
• Shape factors and view factors
• Empirical correlation equations
• You should assume that we will not provide any other formulas or relationships. Keep this in mind when preparing your double-sided A4 formula sheet.

Additional notes:

The exam will still last 2 hours. However, it will now consist of three problems instead of the previous four.

Contents:

• Fundamentals of heat conduction: Fourier’s law, thermal conductivity, thermal diffusivity
• Steady-state and transient one-dimensional heat conduction problems
• Transient heat conduction in lumped-parameter systems
• Multidimensional heat conduction problems, numerical treatment
• Fundamentals of convective heat transfer: differential balance equations, boundary-layer equations, derivation of dimensionless numbers
• Nusselt correlations for forced and free convection in single-phase heat transfer
• Heat transfer in condensation and boiling
• Fundamentals of radiative heat transfer, absorption, emission, transmission, black and gray bodies
• Heat transfer between black and gray bodies
• Analogy between heat and mass transfer
