据文献报道water only cyclone（WOC）,一种离心重力收集技术，可以替代泡沫浮选技术处理煤的细颗粒（小于0.5mm）。该技术解决了泡沫浮选技术以及dense-medium cyclone 技术固有的限制，因为该技术不需要化学或人工介质。目前，该技术还不完善，因为没有对各个变量因素进行评估。本文就是建模评估了下，并流体力学分析了下。就不逐字翻译了，摘要里没说得出啥结论了。
不过，有几个概念稍微查一下了解一下。
泡沫浮选（froth flotation）Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. Historically this was first used in the mining industry.
dense-medium cyclone 过程大致如下：A mixture of raw coal and dense medium enters the cyclone at a predetermined flowrate and pressure. A vortex is formed, and the high density reject forced to the outside to the underflow orifice discharge, also called the spigot. The cleaned coal goes longitudinally down the axis of the cylone and leaves the cyclone through the overflow orifice, also called the vortex finder. From the overflow orifice, the coal goes into the overflow chamber, and is discharged to the next stage of the process.
没看全文，这个woc可能就是用水作为介质通过控制工艺条件实现分离吧。
