Abstract
A boundary element numerical scheme for a flowing mixture of solid particles
and a fluid is developed within the context of mixture theory. Major differences
between the two in literature on the subject are studied, these are typically
employed theories called the averaging approach and mixture theory. A
numerical technique applied is the boundary element method based on velocityvorticity
formulation of general equations describing the flow of a twocomponent
mixture of a Newtonian fluid and a granular solid. Integral
representations for conservation and field functions, based on parabolic diffusion
fundamental solution, are presented. Special attention is focused on the
mechanical interaction between the mixture components.
