Assignment to Modules

Further Information

Courses are together with exams the building blocks for modules. Please keep in mind that information on the contents, learning outcomes and, especially examination conditions are given on the module level only – see section "Assignment to Modules" above.

additional remarks The lecture series will be given as video streams. The current video will be online 1 week ahead of the respective date of the class. On the date a zoom conference is offered where participants can pose their questions to the contents of the lecture. For further details please see Moodle. Heat transfer: Transient conduction: Fourier´s exact solution for the temperature equalisation in plate/cylinder/sphere; heat conduction in semi-infinite solid; Green´s function of Fourier´s differential equation Extended surfaces: Energy balance with variable cross sectional area; effectiveness and efficiency of fins; optimisation of a fin profile Heat transfer with heat source: Spatial varying heat source density; phase change as heat source; melting-solidification ("Stephan-problem"), boiling-condensation (boiling curve according to Nukijama; correlations) Heat transfer in internal flows: Critical Reynolds-number and entry length; laminar fully-developed flow in tubes; thermal entry region; correlations for further geometries and turbulent tube flow Radiation Direction dependent emission; view factors; diffusive radiation between grey surfaces; detailed form of Kirchhoff´s Law. Mass transfer: Mass transfer and phase equlibria: concentrations; calculation of phase equilibria; driving force of mass transfer. Diffusion and convection: diffusion coefficient (gas and liquid), Fick's law of diffusion, molar and mass flux, basic equations, special cases (equimolecular diffusion, unimolecular diffusion, dilluted solution), Mass Transfer two phases: equations for mass transfer (²-model), film theory, overall-model and overall mass transfer coefficient, theories of determining the mass transfer coefficient (film theory, penetration theory (surface renewal theory), analogy heat and mass transfer)
