Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The model of filtration of a suspension in a channel is constructed within the framework of the diffusive approximation with regard to disperse component diffusion and deposit formation. The system of equations is reduced to the convective diffusion equation in integro-differential form. The equation obtained is integrated numerically. The constitutive parameters of the problem considered are established. Certain calculation results which illustrate the effect of the diffusive particle fluxes and the constitutive parameters on suspension dynamics in the channel are discussed. The behavior of mean filtrate flow as a function of time is analyzed for various values of the constitutive parameters.
