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会遇到，对两相流的理解有助于改进设计，从而提高能源系统的性能。例如，液体燃料在喷气发动机或柴油发动机中的燃烧效率由液滴的形成及其随后的汽化来控制。因此，理解液体燃料破碎成液滴是这些燃烧装置的设计的基础。主要申请人（Birouk博士）的大部分研究都集中在这一领域，他的实验室有两个试验台，专门进行从液体喷射、破碎和液滴形成到汽化和随后燃烧的研究。这些试验设施包括一个亚音速风洞和一个压力燃烧室，它们能够模拟发动机试验条件。

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.
