Magneto-microfluidic system for finishing micro-channels

Magneto-microfluidic system for finishing micro-channels
Type:Master Thesis

Dr. Kirill Poletkin

Field of Study:

Mechanical engineering, physics

Links:Spin & Photon Applications (SPA) Laboratory

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).    

Magneto-microfluidic system


Starting date: as soon as possible

Contract duration: 6 months

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.
