| 總結: | Microfluidics is a field of science and technology that focuses on the processing
and manipulation of liquids or fluids with a scale of 10-9 to 10-18 liters. Microfluidic
systems can be divided into several types based on the flow of the fluid such as
droplet-based microfluids. Droplet-based microfluids utilize two types of
immiscible fluids to form a discrete flow that resembles a droplet. This kind of flow
is achieved using droplet generator. Droplet-based microfluidic systems are widely
used in research and industry due to the various fluid flow properties that aid in
analysis and manufacturing. Despite having various advantages, microfluidic
systems including droplet generators have a complicated, costly, and time-
consuming process. In this research, droplet generator is fabricated using 3D
printing. Through 3D printing, droplet generator fabrication become simple, fast
and low cost. The droplet generator that has been successfully fabricated is then
tested for its performance. Flow rate and height of the generator droplet channel
variation testing was also carried out to determine the effect of these factors on the
formed droplets.
Through several iterations, a droplet generator with a channel height of 0.5 mm and
a width of 1 mm was successfully fabricated using the 3D printing method. The
droplet generator can produce monodispersity droplets with an average length of
0.35 cm and a formation frequency of 26 droplets/minute at Qc = Qd = 2.5 ml/hour.
Tests at various flow rates found changes in the length and frequency of droplet
formation. Besides the same changes that are found in flow rates variation testing,
at an inlet channel height of 1 mm, changes in droplet formation process are also
observe. The change in formation causes the length and formation frequency of
produced droplet to become unstable. |
