Modeling of rheological properties of viscoplastic materials in food technologies

Abstract

The article considers the problem of viscoplastic Bingham fluid flow in a rectangular channel of the longitudinal type. There has been developed the mathematical model that allows to obtain analytic expressions for the flow field boundaries of the solid core and its velocity that enables solving of the engineering problems in determining the quantities of liquid flow rate and energy dissipation, as well as making calculations of the working chamber of auger machine.
