Effect of Batch Dissimilarity on Permeability of Stacked Ceramic Foam Filters and Incompressible Fluid Flow: Experimental and Numerical Investigation

Ceramic foam filters (CFFs) are used to remove inclusions and/or solid particles from molten metal. In general, the metal poured on top of a CFF should reach certain height form pressure (metal head) required prime filter. For estimating head and obtaining permeability coefficients CFFs, experiments essential. Recently, electromagnetic priming filtration aluminum with low high grades CFF, i.e., 30, 50 80 pore per inch (PPI) have been introduced. Since then, there has interest in exploring possibility further inclusion entrapment refinement by using force filter stacked CFFs. The successful execution such trials requires profound understanding concerning parameters filters. Such data were deemed not exist prior this study. As result, study presents experimental findings measurements for stacks three PPI commercial alumina CFFs different industrial batches compares numerically modelled as well previous research works. Both numerical showed good agreement results. deviation between experimentally obtained lies range 0.4 6.3%.
