| 1 | CFD investigation of dense phase pneumatic conveying at a pipeline enlargement显示文摘The practice of stepping a conveying line is not new and there are many examples in industry; however, the details of the flow behaviour at the step have not been extensively studied. Three step geometries were modelled: an 'abrupt' step and two 'gradual' step-up geometries from a pipe bore of 75-100 mm. The flow behaviour of a single plug of material passing through these geometries was investigated using the 'Eulerian' CFD model from Fluent. Solids volume fractions were recorded at 0.01 s time steps at several point locations, and visualised throughout the pipe. | Don McGlinchey Andrew Cowell Ryan Crowe | 2012 | Particuology2012，10，2： | 10 |
| 2 | 性能接近线性稳压器的下一代移动DC-DC转换器显示文摘今天的手机不断向小型化和薄型化发展。技术尺寸方面的进展是一个关键问题,可以决定产品开发的命运。同时,由于移动器件的尺寸不断变小,元件尺寸和元件数量也必须减小。元件的布置变得更加重要,抗干扰与低噪声成为工程师工作的一部分。但是,有一些限制因素正在制约这种尺寸缩小的趋势。第一个因素是手机每增加一个新特点,其功耗也要相应增加。最明显的例子是,10年前显示屏的功耗不到50mW,今天已上升到150mW-200mW,预计几年后将上升到300mW-500mW。此外,还有多媒体处理器,相机模块、电视调谐器等等,很容易看到为什么手机的功耗不断增加。 | Andrew Cowell | 2007 | 电子产品世界2007，14，5： | 2 |
