Deep bed filtration rate in porous media
Ch. 030011.
Filtration problems are investigated when calculating foundation fortifying in free soil, when planning tunnels and underground structures to make watertight dividers in porous rock. Amid the filtering of a liquid with tiny particles through a porous frame, some of the particles are trapped in the little pores and form immovable sediment. A 1D model of filtration of similar particles transported by the carrier fluid in a homogeneous porous structure is considered, the filtration function is presumed to be nonlinear. A suspension or colloid is injected into a porous sample filled with clean water and gradually displaced. The growth rate in time of the particles concentrations at a given point of the porous sample is studied. Depending on the particle size, the growth rate of the trapped particles concentration either decreases monotonically with time, or first increases and then decreases. For the nonlinear filtration function, the conditions for the existence of an inflection point on the graphs of the suspended and trapped particles dynamics are obtained.

Every discrete dynamical system (cascade) generated by a homeomorphism induces a continuous dynamic system (flow) — a suspension. However, not every flow is equivalent to a suspension over a cascade, a necessary and sufficient condition for this is the existence of a global section for the flow. In the case of the existence, the flow ...

Injectivity decline due to injection of colloidal suspensions and emulsions occur in numerous areas of geo-energy production, geo- and environmental engineering. This phenomenon is attributed to colloidal capture by porous media resulting in permeability decrease. The shortcoming of the traditional analytical model predicting injectivity decline is the assumption of constant filtration coefficient (probability of the capture) leading ...

One of the constructions for obtaining flows on a manifold is the construction of a suspension over a diffeomorphism. S. Smale showed that suspensions over conjugate diffeomorphisms are topologically equivalent. The converse is not true in the general case. A classic illustration of this fact are examples of non-conjugate diffeomorphisms of a circle whose suspensions ...

A one‐dimensional deep bed filtration model of a polydisperse suspension or colloid in a porous medium is considered. The model includes a quasilinear system of 2n equations for concentrations of suspended and retained particles of n types.

An algebraic variety X is called a homogeneous variety if the automorphism group Aut(X) acts on X transitively, and a homogeneous space if there exists a transitive action of an algebraic group on X. We prove a criterion of smoothness of a suspension to construct a wide class of homogeneous varieties. As an application, we ...

The problems of filtration in porous media are in demand when strengthening
foundations and building waterproof walls in rocks. Deep bed filtration of a highly
concentrated monodisperse suspension in a homogeneous porous medium with size-exclusion
particle retention mechanism is considered. When filtering a suspension in a porous medium,
some solid particles get stuck on the porous frame and form ...

We present results of nuclear magnetic resonance (NMR) experiments in superfluid 3He in two samples of nematic aerogel consisting of nearly parallel mullite strands. The samples were cut from the same piece of the aerogel, but one of them was squeezed by 30% in the direction transverse to the strands. In both samples the superfluid ...

loose soil to create a solid foundation, the movement of groundwater with solid impurities near
underground structures, and many others. A model of two-sized deep bed filtration particles

competition of pores and various size particles ...

Magnetic materials generate demagnetizing field that depends on geometry of the sample and results in a shift of magnetic resonance frequency. This phenomenon should occur in porous nanostructures as well, e.g., in globally anisotropic aerogels.
