The Bubble-Point Test according to BS 3321 is a standard testing procedure to examine the quality of filtration media by identifying the size of the largest pore. The implementation of this testing procedure is fast and easy compared to other quality tests.
Unfortunately the determination of maximum pore sizes with the Bubble-Point Test in its basic form is only valid for perfectly cylindrically shaped pores. To apply the procedure on woven wire meshes, showing a variety of pore geometries, the so called capillary correction factor is needed. This factor usually has to be determined empirically by conducting a vast number of laboratory measurements.
GKD uses numerical tools to replace the time consuming capillary correction factor determination process by a simulation model. This multiphase simulation model makes it possible to immediately find a sturdy value for the capillary correction factor with only one computation necessary, regardless of the filter pore geometry....
