Abstract
We describe a simple experiment involving spheres rolling down an inclined plane towards a bottleneck and through a gap. Results of the experiment indicate that flow rate can be increased by placing an obstruction at optimal positions near the bottleneck. We use the experiment to develop a computer simulation using the PhysX physics engine. Simulations confirm the experimental results and we state several considerations necessary to obtain a model that agrees well with experiment. We demonstrate that the model exhibits clogging, intermittent and continuous flow, and that it can be used as a tool for further investigations in granular flow.

我们描述了一个简单的实验，涉及球体沿斜面滚向瓶颈并穿过间隙。实验结果表明，在靠近瓶颈的最佳位置放置障碍物可以提高流量。我们利用这个实验开发了一个使用PhysX物理引擎的计算机模拟。仿真结果证实了实验结果，并提出了建立与实验结果吻合的模型所需要考虑的几个问题。我们证明，该模型显示堵塞，间歇和连续流动，它可以用作进一步研究颗粒流动的工具。收稿日期:2015年11月22日，收稿日期:2016年2月19日;编辑:L.

期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
