Lee E.Chu J.-W.Hsu J.-P.2019-05-152019-05-15199900219606https://scholars.lib.ntu.edu.tw/handle/123456789/408505The sedimentation behavior of a concentrated suspension of charged spherical particles is investigated theoretically. The sedimentation potential is evaluated taking the effect of double layer polarization into account. A cell model is adopted to describe the present multientities system, and a pseudospectral numerical scheme is used to solve the governing electrokinetic equations, which comprise a Navior-Stokes equation for flow field and a Poisson equation for electric field. Several interesting phenomena, which are absent if double layer polarization is neglected, are observed. For example, the ratio (E*/U*), E*, and U* being, respectively, the scaled sedimentation potential and the scale velocity, has a minimum if the electrical potential is low, and has a maximum if it is high. ? 1999 American Institute of Physics.[SDGs]SDG14journal article10.1063/1.4791032-s2.0-0000200579https://www.scopus.com/inward/record.uri?eid=2-s2.0-0000200579&doi=10.1063%2f1.479103&partnerID=40&md5=ec23e9c711008b3560c7537248c01024
