Granular stream was created with Gaussian horizontal velocity distribution, and the granules pile up when falling on the ground. The ideal model predicts the pile should be Gaussian in shape but certain properties of granular matter can deform this ideal accumulation. After taking these factors into account, the pile surface evolution equation was acquired, and the theoretical prediction accorded with the experimental data very well. Finally, a new approach of mixing granular materials was proposed.
