Modelling of solid particle aggregation dynamics in non-wetting liquid medium

摘要: The aim of this work is to re-examine and, if need be, discuss or modify several the elements classical aggregation dynamics models and adapt them case in non-wetting media particularly alumina inclusions a turbulent flow liquid steel. As proved by experiments models, solid particles contact are linked gaseous bridges which may pre-exist prior aggregate formation. In paper, role these cavities process considered. particular, complete calculation interaction force between hydrophobic surfaces (Bjerkness–Ruckenstein model) performed. Main aspects envisaged particular conditions result from non-wetting. Hydrodynamic interactions modified non-wetting, thus collision efficiency coefficient kernel. fragmentation kernel aggregates, however, larger extent equal zero most cases. Numerical applications presented reference (alumina steel). A general procedure use model other situations given too.
