REG: Acquisition of a Phase Doppler Particle Analyzer (PDPA) for Characterization of Droplet-Based Processes

CTS-9901375 Enrique J. Lavernia，UC Irvine将获得相位多普勒粒子分析仪（PDPA），用于在UCI机械工程和物理系进行金属喷涂和材料相关液滴过程的研究。 这是一个研究设备补助金（REG）的请求。 该设备将用于测量金属喷涂中的液滴尺寸分布、气体和液滴速度。 研究结果将对理解喷射成形中的基本现象、流体动力学与材料结构特性之间的关系、改进喷嘴设计以及作为模型开发的参考基础产生影响。该设备将用于NSF、DOD、NASA、SNL和工业界赞助的多个研究项目以及本科生和研究生教育。 如果成功，PDPA用于熔融金属喷涂将导致对各种基于液滴的制造工艺的更好理解，包括纳米结构涂层。 该研究对铝产品具有直接的工业相关性。

CTS-9901375Enrique J. Lavernia, UC IrvineA phase Doppler particle analyzer (PDPA) will be acquired for conducting research on metal sprays and materials-related droplet processes in the Departments of Mechanical Engineering and Physics at UCI. This is a request for a research equipment grant (REG). The equipment will be used for measurements of droplet size distribution, gas and droplet velocities in metal sprays. The results will have impact on understanding basic phenomena in spray forming, the correlation between the fluid dynamics and resulted material structure properties, enhancing nozzle design, and as a reference base for model development.The equipment will be used for several research projects sponsored by NSF, DOD, NASA, SNL and industry, as well as in undergraduate and graduate education. If successful, the use of PDPA for molten metal sprays will lead to improved understanding of various droplet-based manufacturing processes, including nanostructured coatings. The research has immediate industrial relevance to aluminum products.
