项目摘要

Objectives: The proposed research program aims at continuing the study of the generation and propagation of unsteady compressible flow phenomena, with and without chemical heat release, at millimeter and sub-millimeter scales. Based on these findings, a number of biomedical and aerospace applications will be pursued in the area of high-power density microsystems.Scientific approach: Our approach is based on the experimental observation of compressible flow phenomena at small scale using specially-built devices and on developing simple analytical models to explain the experimental observations. We then use this new knowledge to develop novel devices exploiting these phenomena.We have developed a unique expertise in the experimental investigation of shock waves in millimeter- and micron-scale channels and we will leverage this capability in the study of combustion waves in pre-mixed gaseous mixtures and monopropellants at those scales. In particular, we will investigate if the usual combustion scaling laws and propagation regimes can be extended down to the sub-millimeter scale using appropriate initial conditions (especially elevated pressure) and ignition techniques. If successful, these combustion waves will be used in original miniaturized propulsion and actuation systems.Novelty and significance:There is great interest in continuous micro-combustion for various MEMS devices (engines, fuel cells, etc.) but only few studies have investigated the propagation of unsteady combustion waves at small scales, and never at the micrometer scale of our unique experimental facilities. So this should produce valuable new knowledge that can potentially be exploited in the design of novel high-power density microsystems. Then, as we have successfully been doing for the past 20 years, these innovative devices will be patented and further developed with commercialization partners, leading to value and job creation right here in Canada.

目的：拟议的研究计划旨在继续研究不稳定的压缩流现象的产生和传播，并在毫米和亚毫米尺度上进行有或没有化学热释放。基于这些发现，将在高功率密度微型系统领域进行许多生物医学和航空航天应用。科学方法：我们的方法基于对使用专门构建设备的小规模压缩流现象的实验性观察，以及开发简单的分析模型来解释实验观察。然后，我们使用这些新知识来开发利用这些现象的新型设备。我们在毫米和微米尺度通道的冲击波实验研究中开发了独特的专业知识，我们将在这些尺度上的预混合气体混合物和单寄生植物的燃烧性波中利用这种能力。特别是，我们将使用适当的初始条件（尤其是升高的压力）和点火技术来调查是否可以将通常的燃烧缩放定律和传播方案扩展到亚毫米尺度。如果成功的话，这些燃烧波将用于原始的微型推进和致动系统中。NOVELTY和重要性：对各种MEMS设备的连续微燃烧（发动机，燃料电池等）的连续微燃烧非常感兴趣，但是只有很少的研究调查了在小尺度上不稳定的连击波的繁殖，从来没有在小尺度上，我们的独特实验性的实验性的实验性量表。因此，这应该产生有价值的新知识，这些知识有可能在新型的高功率密度微系统的设计中被利用。然后，正如我们在过去20年中成功做到的那样，这些创新设备将获得专利，并通过商业化伙伴进一步开发，从而在加拿大获得价值和创造就业机会。
