Development of a Full-Field Vorticity Measurement Technique for 3-D Unsteady Flows

这项研究将展示一个立体，双相机系统跟踪激光照射粒子的能力，以产生复杂流动中的非定常，三维涡度图。该技术依赖于利用有限厚度的二维激光照明片。如果成功，这种非侵入式的三维诊断技术将广泛应用于复杂速度场和涡度场的实验测定。在其他用途中，这些信息对于评估当前的数值计算方案至关重要。

This research will demonstrate the capability of a stereoscopic, two- camera system for tracking laser-illuminated particles to produce unsteady, three-dimensional vorticity maps in complex flows. The technique depends on utilization of a finite thickness two- dimensional sheet of laser illumination. If successful, this non- intrusive, three-dimensional diagnostic technique would be widely applicable in experimentally determining complex velocity and vorticity fields. Among other uses, this information is crucial in evaluating current numerical computation schemes.
