Beyond Kozeny–Carman: Predicting the Permeability in Porous …

Web14 aug. 2024 · We find that semiempirical coefficients such as the Kozeny-Carman coefficient depend markedly on the statistical distribution of pores and throats. This dependence can be quantified as a constriction factor that incorporates the pore size distribution to yield accurate predictions of permeability of random fibrous media. WebIn this paper, an attempt has been made to investigate the possibility of using coal sludge to seal a landfill site by presenting the results of their compressibility and permeability tests. Coal sludge is a fine-grained waste from the coal enrichment process, and its permeability is also highly dependent on its degree of consolidation. The tests were carried out in a … onshift help desk https://foxhillbaby.com
