Simulation Results

To design high quality and efficiency discharging system, according to the analysis of strength and the study of discharging principle for bulk materials between general silo and central cone silo with discharge arms, their theoretical model and simulation model are established. Based on the theoretical calculation and simulation results, it is proved that the central cone silo which has a rotary discharge arm or discharge arms revolving around the central cone has advantages with discharging the difficult bulk materials, which could efficiently prevent the harmful discharging such as bridging, rat-hole and so on. Controlling the outflow of bulk materials, it is easy to automatically discharge the bulk materials and improve the efficiency of silo system. The result shows that the central cone is practical and the discharging way provides a new program for solving technology problems in discharging the difficult bulk materials.

Numerical Formulation

This paper presents the development of a theoretical model and simulation analysis for the discharging process that takes place in a porous medium initially saturated with ink. During the discharging process the porous material provides enough surface area to hold the fluid by capillarity effects. It was found by the numerical solution that the velocity profile through the porous region was uniform and the backpressure had a linear behavior as function of time. A parametric study also revealed that the permeability, void volume and surface tension have a significant effect on the pressure drop. The numerical formulation was validated with experimental data and good agreements were found between both data sets.
