Charakterizace proudění v mikrofluidních zařízeních vyrobených 3D tiskem

Abstract

This bachelor's thesis deals with the characterization of flow in microfluidic devices made by 3D printing. Microfluidic devices, which work with very small volumes of fluids, have many advantages, such as efficient mass and heat transfer within them or simple implementation of multiphase processes. The thesis describes the construction of microfluidic devices, their advantages and disadvantages, and their use in various fields. Emphasis is placed on the use of 3D printing for the production of microfluidic devices, which can solve some problems associated with their production. Furthermore, the shape deformations of the channel caused by 3D printing are described for these devices. For these devices, the mean residence times and other RTD characteristics were experimentally determined. The work is also supplemented by conventional microfluidic devices made of metal, for which an experiment with a tracer substance was also carried out in various configurations. Finally, the thesis includes a CFD flow simulation for some selected microfluidic devices.
