当人们看到艺术家凯特·麦克道威尔(Kate Macdowell)的作品时,脑海中会情不自禁地浮现出这样一段话——段来自英国学者、《纳尼亚王国传奇》作者C.S.Lewis的名言:"对于美,我们从不满足于远观。尽管上帝为证,美已是无上的恩典。我们希求无法诉诸语言的情感——我们想与所见的美产生关联,想将美据为己有,想周身沐浴其中,甚至——想成为美的一部分。" 相似文献

One challenge of generating a liquid aerosol is finding an efficient way to break up bulk amounts of the compound into micron-sized droplets. Traditional methods of aerosol generation focus on the principle of creating the liquid droplets by blowing air at high speed over or through a liquid. In this study, a novel micropump droplet generator (MDG) is proposed based on a microfluidics device to produce monodisperse droplets on demand (DoD). The micropump design was employed to both pump the fluid into the air and to encourage droplet breakup and aerosol formation. Computational simulation modeling of the new MDG was developed and validated with comparisons to experimental data for current generators. The device was found to produce an aerosol similar to a vibrating orifice DoD device. Most importantly, the input power required by the newly proposed device (MDG) was several orders of magnitude below existing DoD generators for a similar droplet output. Based on the simulation results obtained in comparison with current DoD generators, the MDG device performed effectively at higher frequencies, smaller nozzle diameters, and regardless of the liquid viscosity of the solution. 相似文献
