Appendices to the data collections of the following publications: - Publication A: Study on the influence of solids volume fraction on filter cake structures using micro tomography - Publication B: Neighborhood Relationships of Widely Distributed and Irregularly Shaped Particles in Partially Dewatered Filter Cakes - Publication C: Insight into filter cake structures using micro tomography: The dewatering equilibrium - Publication D: Network model of porous media – Review of old ideas with new methods - Publication E: Wetting behavior of porous structures: Three-dimensional determination of the contact angle after filter cake dewatering using X-ray microscopy The data collection contains tomographic images (ZEISS Xradia 510 Versa) of partially dewatered filter cakes according to VDI 2762. The images include filter cake structures from additional particle systems such as mica, limestone, quartz, dolomite and glass particles and thus complement the reference system of aluminum oxide particles (publications A to E). All particles are between 50 and 200 µm in size, and their shape varies from spherical to cubic to fibrous and plate-like. https://opara.zih.tu-dresden.de/xmlui/handle/123456789/1950 2026-04-29T05:52:10Z 2026-04-29T05:52:10Z Löwer, Erik https://opara.zih.tu-dresden.de/xmlui/handle/123456789/1962 2021-08-23T14:00:43Z 2021-01-01T00:00:00Z

fully saturated and dewatered filter cakes at different resolutions Löwer, Erik Appendix to Publications A to E with investigations of different particle systems (material, size and shape variation). X-ray tomography image of fully and partially dewatered filter cakes. The initial slurries contains mica, dolomite, quartz, limestone or glass particles suspended in a potassium iodide-glycerol brine. The different shaped particles were separated by cake-forming filtration followed by dewatering. All filtration and dewatering experiments took place in an in situ apparatus within the Zeiss Xradia 510 X-ray microscope. The filter cake is dewatered until the minimum degree of saturation is reached within the pore space. A scan is taken at the equilibrium state before and after dewatering. A small section in the center of the desaturated filter cakes was additionally measured at a significantly smaller field of view and higher resolution in order to be able to determine the local contact angle in addition to the saturation distribution and the size of the individual liquid bridges. see note parameter.png in each measurement file for further measurement and reconstruction parameters
