简介：正常冲击波，在一个机翼上终止一个本地超声的区域，限制它的表演并且成为来源高加速冲动的噪音。使用被动控制瓦解被建议冲击波。这个方法获得的流动结构的细节数字地被学习。一个新边界条件被开发了，它的应用程序的结果在嘴流动对实验被验证。崩溃被证实了并且详细说明流动细节的分析的冲击波的方法被介绍。由渐渐的压缩的一个冲击波的替换完全改变高速度的来源它的减小的冲动的噪音和熊潜力。关键词接近音速的流动-冲击波边界层相互作用-被动控制CLC数字O357.4+2

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：永久磁铁同步马达(PMSM)可以与掉进某个区域的全身的参数或在某些工作条件下面经历混乱行为，它威胁安全、稳定的操作马达驱动。因此，学习在PMSM控制或压制混乱的方法是重要的。在这个工作，Takagi-Sugeno(T-S)为PMSM的模糊冲动的控制模型经由T-S建模方法论和冲动的技术被建立。基于新模型，为PMSM的asymptotical稳定性和指数的稳定性的控制条件被Lyapunov方法导出。最后，一个说明例子也被给显示出获得的结果的有效性。
