IMT 21-16 Master Thesis: Magneto-microfluidic system for finishing micro-channels

Karlsruhe Institute of Technology (KIT) - KIT - Helmholtz Association

Karlsruhe, Germany

Work group:

Institute of Microstructure Technology (IMT)

Area of research:

Diploma & Master Thesis

Job description:

The main goal of project is to design and develop a magneto-microfluidic system in order to perform polishing of micro-channels with a complex geometry and to characterize this process. The polishing process will be done using magnetic nanoparticles with abrasive properties. The student will be heavily involved in developing a PMMA-based system for this purpose and in characterizing the channels geometry by means of white light interferometer. By the end of the project the student will demonstrate the magneto-microfluidic system and preliminary results of the study of the polishing quality depending on different regimes of the system (average velocity of the suspension in micro-channel, strength of magnetic field etc.) and different suspensions (oil, magnetic abrasive suspension with different shapes of magnetic nanoparticles).

Further information on the Institute of Microstructure Technology (IMT):

An ideal candidate should demonstrate the following knowledge and skills:
• background in fluid mechanics (Newtonian fluid, Couette and Poiseuille flows);
• experiences in using FEM tools – COMSOL, ANSYS etc;
• to be familiar with computer-aided systems (CAD) –SolidWorks.

Field of study: Mechanical engineering, physics
