Opis
Izvleček:A BEM numerical scheme for a flowing mixture of solid particles and a fluid is developed within the context of mixture theory. The major differences between the two fundamental theories, i.e. the averaging theory and the mixture theory, are studied. The numerical technique applied is the BEM based on the velocity-vorticity formulation of general equations describing the flow of a two-component 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 focussed on the mechanical interaction betwen the mixture components.
