Steady and Transient Motion of Spherical Particles in Viscoelastic Liquids
1. Introduction The motion of a spherical particle through a fluid with non-Newtonian rheological properties is a well-studied problem with a broad range of practical application from sedimentation of muds and slurries to processing of filled polymer melts. As a benchmark problem for computational rheology and the evaluation of numerical codes (cf. Hassager, 1988), the sedimentation of a sphere...

15 صفحه اولElectrophoretic Motion of Two Spherical Particles with Thick Double Layers
The electrophoretic mobilities of two interacting spheres are calculated numerically for arbitrary values of the double-layer thickness. A general formula for the electrophoretic translational and angular velocities of N interacting particles is derived for low-zeta-potential conditions. The present calculation complements the well-studied case of thin double layers. The results are compared wi...
متن کاملThe pair distribution function and structure factor of spherical particles
An envelope function is derived which multiplies the pair distribution function (PDF) of an infinite solid to obtain that of a spherical particle with the same crystal structure. Distributions of particle sizes are then considered, and the analytical results are used to predict the distribution from a PDF obtained experimentally. The peak broadening for the associated structure factor, expresse...
متن کاملthe underlying structure of language proficiency and the proficiency level
هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
