[P01-20] Computations of Two Fluis Consisting of Newtonian and Bingham Fluids Moving between Multiple Static Solid Objects
Keywords:the finite volume method, Bingham fluid
The two-fluid system consisting of Bingham and Newtonian fluids is sometimes seen in the area with multiple solid objects, such as mortar flows between aggregates and grouting-materials flows in rock fractures. In this study, the phase-averaged governing equations are discretized with the finite volume method with the collocated grid system. The dam-break flows of the Bingham fluids surrounded by the Newtonian fluids were calculated with the present method. From the numerical experiments, the effects of the non-dimensional yield stress of Bingham fluids are investigated together with the number of the fixed square objects in the computational area.
