Summary: | Microbubbles are known for their many
applications. Recently there has been new findings regarding the growth
of susceptible microalgae through microbubble aeration. There are three methods
used to generate microbubbles for this microalgae strain. Unfortunately, for some
methods, the cost of generating microbubbles
is still high. However, fluidic oscillators
can be used to produce microbubbles at a
reasonable cost. There are two types of fluid oscillators: single loop and double loop. This study
determined the bubble size produced with these oscillators. Bubble size data
was recorded using a high-speed camera at air flow rates of 6 LPM, 9 LPM, 12 LPM, and 15
LPM, and utilized 10 µm microporous shafts as the diffuser. The data were processed using ImageJ software. The results showed that the size of
the bubble using a single loop fluid oscillator was smaller than that of the
double loop fluid oscillator. The smallest bubble size was obtained in a single loop fluid oscillator
with an airflow of 6 LPM. |
