Comparison of Fine Particle Clogging in Soil and Geotextile Filters
This paper addresses the differences in the extent of clogging associated with fine particle transport in soils and geotextiles. A common experimental set-up was designed for soil and geotextile filtration. Tests were conducted using a nonwoven, needle-punched geotextile filter sample permeated with fine particle suspensions under constant flow rate. The results were compared with those from si...
متن کاملConstriction Size of Geotextile Filters
Filtration performance of nonwoven geotextiles strongly depends on pore opening constriction size, i.e., the minimum opening size of flow channels across the geotextile. Currently available methods of pore opening characterizations do not provide accurate information about the constriction size. This paper presents the constriction size distributions of eleven nonwoven geotextiles commonly used...
متن کاملClogging of Multigraphs as Toy Models of Filters
In this paper we model filters as networks of channels. As suspension (fluid with particles) flows through the filter, particles are trapped and clog channels. We assume there is no flow through clogged channels. The filter becomes impermeable after not all, but only a portion, of the channels clog. In this paper we compute an upper bound on the number of channels that clog. This bound is a fun...
متن کاملA Belief Function Theory Method for Prognostics in Clogging Filters
This paper presents a similarity-based approach for the prediction of the Remaining Useful Life (RUL) of sea water filters placed upstream the heat exchangers of a nuclear reactor condenser. The prognostic approach is developed considering a library of reference degradation trajectories containing parameter observations taken from a set of similar equipments until their failures. The prediction...
متن کاملEffects of Ionic Strength on Fine Particle Clogging of Soil Filters
The effects of ionic strength of the permeating fluid on the clogging of soil filters and drainage layers are addressed using both experimental and modeling investigations. In the experimental phase, a sandy soil representative of soil filters was permeated with pore fluids containing kaolinite particles. The ionic strength of the solutions was changed using different concentrations of NaOH and...
