Ultra-high-speed camera for characterization of complex fluid physics

我们要求一个超高速摄像机，以表征各种理解不足，流体动力学问题。超高速摄像机的引入正在改变研究界在最小空间和最快时间尺度上研究流体物理的能力，包括从涡旋混合层到爆炸物理，以及从冲击波动力学到两相气泡流的各种问题。直到最近，上述这些问题只能用点测量技术在积分尺度上测量，并且需要进行大量的推测来推断这些结果。我们现在，随着高速摄像机分辨率和感光度的重大改进，有机会在多尺度现象的复杂流动的表征方面取得新的突破，这对我们对数值模型的基本理解和验证至关重要，也将指导加拿大工业在可再生能源，航空航天，生物医学和国防部门的最新发展。

We are requested an ultra-high-speed camera so as to characterize a variety of poorly-understood, fluid dynamics problems. The introduction of ultra-high-speed cameras is changing the research community's ability to study fluid physics at its smallest spatial and fastest temporal scales, over a wide variety of problems ranging from vortical mixing layers to explosion physics, and from shock-wave dynamics to two-phase bubbly flows. Up until recently such aforementioned problems could only be measured at the integral scale with point measurement techniques and much speculation was required to infer these results. We now, with the advent of major improvements in high-speed camera resolution and light sensitivity, have the opportunity to break new ground in the characterization of complex flows with multi-scale phenomena, which will be critical to both our fundamental understanding and validation of numerical models but also to guide Canadian industry with their latest developments in the renewable, aerospace, biomedical and defence sectors.
