Abstract
(type = abstract)
For this study, we consider a filtration system consisting of a periodic arrangement of PEG liquid columns formed between two glass slides; a distribution of water particles moves past these columns and the overall filtration efficiency of the system is determined. We then investigate the impact of higher flow rates, and column spacing on the overall efficiency of the system. We show that for a decreased spacing between columns a higher overall efficiency can be achieved. At a larger spacing rate, larger particle distributions are observed indicating lower capture rates. Decreasing the spacing between columns lowers the overall distribution observed leading to a higher capture efficiency. For higher flow rates, overall particle capture is shown to improve for smaller particle sizes. An increase in overall efficiency values especially for smaller particle sizes is believed to be due to the increased inertial capture of the particles at these higher flow speeds. Detailed results are obtained for these various cases to identify the overall efficacy and efficiency of this unique filtration system. Furthermore, during higher flow rate tests the filtration unit is limited due to the blowing off phenomena of the columns. To quantify this phenomena data was collected at initial signs of column blow off and compared against various non-dimensional flow variables. This data yielded a correlation between a modified capillary number of the slides gap size and the flow rate of the system was obtained. All the results obtained through various experiments help to show the overall effectiveness and viability of a PEG column filtration system.
