SG2222 Micro Fluids 4.5 credits

Examples of processes and applications, chemical synthesis and analysis. Low Reynolds number hydrodynamics, reversibility of low Re flow. Chaotic mixing, Liapunov exponents, Poincare maps. Surface tension, thermocapillary convection, wetting. Electrokinetics. Non-continuum effects. Micro fluidic devices.

The purpose of the course is to introduce concepts and methods that are relevant for understanding the flow of liquids, and its importance for mixing and chemical reactions in geometries of microscopic dimensions. The emphasis is on the microscopic fluid mechanics that is relevant for chemical synthesis and analysis, as well as for micro systems technology.

Prerequisites are general courses in mathematics, basic physics etc. This course should be of interest to graduate and last year students in fluid mechanics, chemistry, biotechnology, micro systems technology etc, so special care is taken to make the material accessible for students with a quite varied background.

English B / English 6

If the course is discontinued, students may request to be examined during the following two academic years.

• PRO1 - Project, - credits, grading scale: P, F
• TEN1 - Examination, 4.5 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Typically one project/seminar per group of two students.
In addition each project is assigned two 'opponents', that read the same material and prepare questions.
A short oral exam.

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
