The Modeling of Dough Mixing with Free Surfaces in Two and Three dimensions
نویسندگان
چکیده
This paper reports work on the two and three-dimensional numerical simulation of dough mixing with free surfaces, that arises in the food processing industry. Free surface flow in a rotating cylinder is investigated when a fluid is mixed in a cylinder with a stirrer. Different dough mixer designs are investigated. The rotating stirrer may be placed either in a concentric or eccentric arrangement with respect to the axis of the vessel being horizontal or vertical. The equations are solved in a three dimensional cylindrical polar coordinate system. The numerical simulation is based on a Taylor-Galerkin finite element formation, with an arbitrary LagrangianEulerian scheme to accommodate free surface movement. Predictions compare closely to equivalent experimental results.

The continuum based approaches don’t provide the correct physics in atomic scales. On the other hand, the molecular based approaches are limited by the length and simulated process time. As an attractive alternative, this paper proposes the Fixed Interfacial Multiscale Method (FIMM) for computationally and mathematically efficient modeling of solid structures. The approach is applicable to mult...
