Engineering Research Equipment Grant: Phase Doppler Particle Analyzer

这项设备赠款提供了一个相位多普勒粒子分析仪 进行需要同时测量 和速度的两个分量。 仪器 基本上是一个双组分，双色激光多普勒测速仪 其已经被增强以执行颗粒尺寸测量。 该设备提供了一种诊断非侵入性工具， 进行粒度分布的点测量， 速度 该设备将成为许多热科学项目的一部分 包括研究旋转系统中的传热和传质， 材料加工，非牛顿流动，燃油喷雾雾化，实验研究 喷雾点火和燃烧，流体取样 暂停，以及其他。 测量粒子的能力 在这些问题中的大小和速度将有助于理解 和进程的发展。

This equipment grant provides a Phase Doppler Particle Analyzer to conduct research which requires the simultaneous measurement of particle size and two components of velocity. The instrument is basically a two component, two color Laser Doppler Velocimeter which has been enhanced to perform particle size measurements. The device provides a diagnostic non-intrusive tool capable of making point measurements of particle size distribution and velocity. This equipment will be part of many thermal science projects including studies of heat and mass transfer in rotating systems, materials processing, non-Newtonian flows, fuel spray atomization and dispersion, spray ignition and combustion, sampling of fluid suspensions, and others. The ability to measure both particle size and velocity in such problems will enhance the understanding and development of the processes.
