Predicting physical clogging of modular paver equipped with filter media
IOP Conference Series: Earth and Environmental Science, 2023 Abstract Porous pavements are simple to retrofit, good at improving the hydrology and quality of the water, but prone to clogging. There is little knowledge on the physical clogging processes through these systems, even though they play a significant role in the lifespan of porous pavements. This study’s objectives were to comprehend the

The Physical Chemistry of Steel Deoxidation and Nozzle Clogging in Continuous Casting
, 2021 Nozzle clogging in continuous casting of steel originates by the adherence of alumina particles and other oxides, precipitated during the liquid steel deoxidation, on the refractory material’s surface. Hence, these particles’ nucleation and growth rates in supersaturated melts are analyzed considering, specifically, the role of the interfacial tensions

Effect of Grain size of Porous Media on Physical Clogging
Journal of Zankoy Sulaimani - Part A, 2006 The effect of size of grains of porous media on physical clogging under constant flow rates was investigated experimentally. A sandy soil having particle size ranging from 355 to 1190 pm, fractioned into seven unisizes, was selected as the porous media" Two types of silt soils (smaller than 63 pm) were used as suspensions, Two concentrations (500 and ...
