简介：在最近的年里，microchannel热exchangers在技术区域的一个大变化被使用了。这些问题之一，它在microchannel技术存在是流动不稳定性，包括在为在特别的二阶段的流动的盒子的microchannels数组的液体maldistribution微蒸发器。解决这个问题的方法之一是在microchannel入口的流动率控制。然而，由于到microchannels的数组的很小的入口经典流动限制设备(与动人的机械部分)将困难适用。为流动率控制的新设备在论文基于dielectrophoresis力量被介绍。为致冷的流动控制使用这台设备的试验性的研究结果在论文被介绍。在应用电压和频率和流动率之间的试验性地获得的关系被介绍为为refrigerants和另外的不稳定的液体使用如此的方法显示出机会。

简介：可变几何学捆绑操纵者(VGTM)有潜力在未来空间应用程序，一个动态模型对系统的动态分析和控制重要工作。在这份报纸，一条途径被介绍由独立变量为VGTM的动态方程建模，它由二双octahedral组成捆绑单位和3-revolute-prismatic-spherical(3-RPS)平行操纵者。在这条途径，二邻近的身体的运动学的递归的关系并且几何抑制被用来推出VGTM的运动学的方程，并且Jourdains速度变化原则被采用建立系统的动态方程。建议动态模型的有效性被数字模拟的比较与软件亚当斯验证。而且，为轨道追踪系统的一个活跃控制器被计算转矩方法设计。控制器的有效性数字地被证明。
