After successful completion of the course, students are able to model typical (relatively simple) problems of momentum, heat, and mass transfer, i.e. to set up differential equations describing the problem, and to solve the model equations under simplifying assumptions.
Basic equations (momentum, energy, mass and entropy balances) in integral and differential form, Reynolds transport theorem, jump conditions, steady and unsteady heat conduction and diffusion processes, convective heat and mass transfer: phase transitions, modelling of unidirectional phenomena (example: tunnel kiln as a counter flow heat exchanger), film flows, boundary layers, natural convection, blunt body flows.
Most process engineering applications are based on momentum, heat and/or mass transfer, i.e. combine aspects of fluid mechanics, thermodynamics and chemistry. Because of the abundance of possible cases (in addition to those of the introductory lecture heat and mass transfer 1), here a method-oriented, deductive approach is chosen, i.e. for some typical (exemplary) problems, the basic equations are correspondingly simplified and solved (`from general to specific '). The goal is the aptitude for the physical-mathematical modeling of (relatively simple) problems as well as the critical use of reference works (eg VDI-Heat Atlas), especially with regard to the applicability of calculation formulas). Special emphasis is placed on analytical solution methods (including Fourier series, similarity and perturbation approaches), which form the basis for numerical solution methods (e.g. spectral methods) or provide test cases for (commercial) simulation software.
The score of two regular tests has to be more than the minimum required to pass the course (normally half of the total score), or the additional test has to be passed. Additional credits may be obtained by active participitation during the course (e.g. presenting exercise examples on the blackboard).
