论文摘要
进一步开发了用于测量液滴尺寸的DeFocus（DFD）技术的两镜深度，以实现较高的空间和时间分辨率，以提高大小和数量浓度的估计值，并为特定应用的光学系统的校准和设计提供其他指南。当冲击波与单滴相互作用时，使用次要雾化的情况来证明该技术和这些改进。这是一个应用程序，在该应用中，必须在原始滴水之后生成的二级液滴的高空间和时间分布的数字密度和大小分布。
The two-sensor depth from defocus (DFD) technique for the measurement of drop sizes in a spray is further developed to achieve higher spatial and temporal resolution, to improve estimates of size and number concentration, and to provide additional guidelines for the calibration and design of the optical system for a specific application. The technique and these improvements are demonstrated using the case of secondary atomization when a shock wave interacts with a single drop. This is an application in which both high spatially and temporally resolved number density and size distributions of secondary droplets generated in the wake of the original drop are necessary.
