Upgrade of a Standard Particle Image Velocimetry (PIV) System to Enable Particle Size Measurement

两相流在许多工程应用中都遇到过，对它们的理解有助于改进能源系统的设计和性能。例如，喷气或柴油发动机中液体燃料的燃烧效率是由液滴的形成及其随后的汽化控制的。因此，理解液体燃料分解成液滴是设计这些燃烧装置的基础。主要申请人（Birouk博士）的大部分研究都集中在这一领域，他的实验室有两个测试平台，专门进行从液体注入、破裂和液滴形成到汽化和随后的燃烧的研究。这些试验设施由亚音速风洞和压力燃烧容器组成，具有模拟发动机试验条件的能力。

Two-phase flows are encountered in numerous engineering applications and their understanding help improve the design and consequently the performance of energy systems. For example, the combustion efficiency of liquid fuel in jet or diesel engines is controlled by the droplets formation and their subsequent vaporization. Therefore understanding liquid fuel breakup into drops is fundamental for the design of these combustion devices. Most of the principal applicant's (Dr. Birouk) research focuses on this area where his lab has two test rigs dedicated to carry out research from liquid injection, breakup and droplets formation to vaporization and subsequent combustion. These test facilities consist of a subsonic wind-tunnel and a pressure combustion vessel which have the capability to simulate engine test conditions.
