AbstractThis course presents the fundamentals of transport phenomena with emphasis on mass transfer. The physical significance of basic principles is elucidated and quantitatively described. Furthermore the application of these principles to important engineering problems is demonstrated.
ObjectiveThis course presents the fundamentals of transport phenomena with emphasis on mass transfer. The physical significance of basic principles is elucidated and quantitatively described. Furthermore the application of these principles to important engineering problems is demonstrated.
ContentFick's laws; application and significance of mass transfer; comparison of Fick's laws with Newton's and Fourier's laws; derivation of Fick's 2nd law; diffusion in dilute and concentrated solutions; rotating disk; dispersion; diffusion coefficients, viscosity and heat conduction (Pr and Sc numbers); Brownian motion; Stokes-Einstein equation; mass transfer coefficients (Nu and Sh numbers); mass transfer across interfaces; Reynolds- and Chilton-Colburn analogies for mass-, heat-, and momentum transfer in turbulent flows; film-, penetration-, and surface renewal theories; simultaneous mass, heat and momentum transfer (boundary layers); homogenous and heterogenous reversible and irreversible reactions; diffusion-controlled reactions; mass transfer and first order heterogenous reaction. Applications.

Prerequisites / NoticeTwo tests are offered for practicing the course material. Participation is mandatory.

Language of examinationEnglish
RepetitionThe performance assessment is offered every session. Repetition possible without re-enrolling for the course unit.
Mode of examinationwritten 120 minutes
Additional information on mode of examinationParticipation on two tests during the semester is required. The first test counts for 10% and the second for 20% of the final grade. Justified absence due to military service or illness (with doctor's certificate) from any test, moves its weight to the next scheduled test or examination. For example, if a student misses the first test, then the second counts for 30% while if s/he misses the second, then the final examination counts for 90% of the final grade.

Repetition: For students repeating the exam only the final examination counts.
Written aidsStandard wissenschaftlicher Taschenrechner (nicht-kommunikationsfähig, keine Computer oder Mobiltelefone), Textbuch (Cussler), 1 DIN A4-Blatt (Vorder- und Rückseite) Formelsammlung, Skript
If the course unit is part of an examination block, the credits are allocated for the successful completion of the whole block.
This information can be updated until the beginning of the semester; information on the examination timetable is binding.
