Fluid physics of cold gas-dynamic spray process

冷气动力喷雾有可能重振澳大利亚制造业和经济，并使其发生革命性变化。它是一种技术先进的柔性自由成形工艺，在航空、汽车、海军和生物医疗领域具有潜在的应用前景。它允许设计从纳米尺度到宏观尺度的功能表面，可以通过在衬底上喷涂任意厚度和密度的材料涂层来制造。喷雾颗粒输送的过程是至关重要的，目前还不清楚。这项研究将对流体物理和喷雾粒子物理进行研究，以获得使该过程节能并扩大其应用范围所必需的必要了解。

Cold gas-dynamic spray has the potential to revitalize and revolutionize the Australian manufacturing sector and economy. It is a technologically advanced flexible free-forming process with potential applications in the aviation, automotive, naval and bio-medical sectors. It allows for the design of functional surfaces from the nano-scale to the macro-scale that can be manufactured by spraying material coatings of arbitrary thickness and density on a substrate. The process of the spray particle delivery is crucial and not understood. This research will investigate the fluid physics and spray particle physics to gain the essential understanding necessary to make this process energy efficient and extend its range of application.
