Numerical simulation of coal stream in tubing transport by 3-dimensional distinct element method

摘要

In this paper, the basic feature of particle system of coal stream is analyzed, the property model of coal stream particle is established by discrete element method according to its characteristics and a moving model is constructed by a simplified Hertz-Mindlin contact, and the coal stream movement is simulated with particle system, which plays an important role in assuring the fidelity and integrality of 3D virtual coal stream in tubing transport scene.
