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 کاملSuspension extraction through an opening before clogging
Fluids with particles in suspension can be extracted through an orifice until particles bridge across the opening and clog it. We derive and study a mathematical model to predict the volume of fluid that can be extracted before clogging. Numerical simulations and closed-form upper and lower bound solutions show the dependency of the expected extracted volume on the volume fraction of particles ...
متن کاملlanguage learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
OPTIMIZATION OF OPENING SIZE FOR CASTELLATED BEAM WITH SINUSOIDAL OPENINGS
Castellated beams are generally provided with hexagonal and circular openings in the web portion. However, in view of structural applications, appropriate size and shape of openings in web are always a major issue of concern. Research work carried out in optimizing sizes of castellated beam with hexagonal openings have reported that castellated beams fail mainly by local failure modes and stres...
