Learning objective
This 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.
Content
Fick'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; Analogies for mass-, heat-, and momentum transfer in turbulent flows; film-, penetration-, and surface renewal theories; simultaneous mass, heat and momentum transfer (boundary layers); homogeneous and heterogeneous reversible and irreversible reactions; diffusion-controlled reactions; mass transfer and first order heterogeneous reaction. Applications.
Literature
Cussler, E.L.: "Diffusion", 3nd edition, Cambridge University Press, 2009.
Prerequisites / Notice
Students attending this highly-demanding course are expected to allocate sufficient time within their weekly schedule to successfully conduct the exercises.
Performance assessment
Performance assessment information (valid until the course unit is held again)
Performance assessment as a semester course
In examination block for
Bachelor's Degree Programme in Chemical Engineering 2006; Version 27.03.2018 (Examination Block Thermodyn. & Transport Phenomena) Bachelor's Degree Programme in Chemical Engineering 2018; Version 26.09.2022 (Examination Block II) Bachelor's Degree Programme in Chemical Engineering 2018; Version 26.09.2022 (Examination Block III)
The performance assessment is offered every session. Repetition possible without re-enrolling for the course unit.
Mode of examination
written 120 minutes
Additional information on mode of examination
During the semester, two interim examinations will be offered to help students assess their Mass Transfer performance and prepare for the final exam. The two interim exams are optional and only contributing to the final grade if they help improve it. They may count together up to 30% (15% each) towards the overall result, depending on student performance.
Written aids
Standard 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.
