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

enrique J. Lavernia， UC irvine将获得一台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雾和材料相关液滴过程的研究。这是一份研究设备补助金（REG）的申请。该设备将用于测量金属喷雾中的液滴大小分布、气体和液滴速度。研究结果将对了解喷射成形的基本现象、流体力学与材料结构性能之间的关系、加强喷嘴设计以及为模型开发提供参考依据。该设备将用于由NSF、DOD、NASA、SNL和工业界赞助的几个研究项目，以及本科和研究生教育。如果成功，将PDPA用于熔融金属喷雾将提高对各种基于液滴的制造工艺的理解，包括纳米结构涂层。这项研究对铝产品具有直接的工业意义。

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.
