Particle flow and collection process in single wire HGMS studies

Abstract

A television system for the observation of HGMS particle flow and buildup on a ferromagnetic wire or small array of wires is described for three geometries. Data for the collection process and a sequence of pictures of buildup are presented for Mn <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> P <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">7</inf> , Mn <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> , and Cr <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> particles collected on 125 μm nickel wires. The wake, formed in some cases downstream from the particle collection, has been studied. Data on the wake is given and compared with published data on wake formation. New results on downstream and upstream collection on a wire as a function of slurry velocity is presented.
