Numerical Analysis of Steady-State Flow of Granular Materials Based of Micropolar Fluid Theory and Discrete Element Method

Key Points

• To analyze steady-state flow of granular materials using micropolar fluid theory and discrete element method for better modeling accuracy.
• Applied micropolar fluid theory for continuous modeling of granular flow.
• Utilized discrete element method (DEM) to represent granular materials as discrete entities.
• Conducted numerical analysis of flow in a one-dimensional infinite slope.
• Successfully replicated velocity and rotation speed distributions from DEM using the continuous model.
• Discovered that the ratio of kinetic to rotational energy follows a log-normal distribution in steady-state conditions.
• Obtained all necessary parameters for analysis from DEM results.
