The Clogging Rules of Ceramic Emitter in Irrigation Using Saline Water with Different EC

Agronomy, 2019
Infiltration irrigation with saline water is a more effective method than drip irrigation to alleviate water scarcity worldwide, but so far, no report has discussed the clogging rules of ceramic emitters, a major component of infiltration irrigation ...

Experiment Investigation and Influence Evaluation of Permeability Ability Attenuation for Porous Asphalt Concrete under Repeated Clogging Conditions

Buildings, 2023
One of the problems that limit the development of porous asphalt concrete (PAC) is that the pores become clogged, which leads to severe deterioration in its permeability performance. This paper focuses on PAC’s permeability characteristics under repeated

Fibre bridging and nozzle clogging in 3D printing of discontinuous carbon fibre-reinforced polymer composites: coupled CFD-DEM modelling

The International Journal of Advanced Manufacturing Technology, 2021
A coupled multiphase model based on computational fluid dynamics (CFD) and discrete element method (DEM) is developed to numerically investigate the extrusion-based 3D printing process of discontinuous carbon fibre-reinforced polymer composites.

Evaluating potential of diatomite as anti clogging agent for porous asphalt mixture [PDF]

, 2016
Clogging is a major problem that occurs throughout the service life of porous asphalt due to the open nature of the mixture itself. Diatomite with characteristic of abrasiveness and porous structure seems to have potential in order to remove the clogging

Metabolic disturbances potentially attributable to clogging during continuous renal replacement therapy

Intensive Care Medicine Experimental, 2023
Background Clogging is characterized by a progressive impairment of transmembrane patency in renal replacement devices and occurs due to obstruction of pores by unknown molecules.

Transport of polymer particles in a oil-water flow in porous media: enhancing oil recovery [PDF]

, 2018
We study a heuristic, core-scale model for the transport of polymer particles in a two phase (oil and water) porous medium. We are motivated by recent experimental observations which report increased oil recovery when polymers are injected after the ...

Exponential clogging time for a one dimensional DLA

, 2007
When considering DLA on a cylinder it is natural to ask how many particles it takes to clog the cylinder, e.g. modeling clogging of arteries. In this note we formulate a very simple DLA clogging model and establish an exponential lower bound on the ...
