Under an SBIR Phase II grant, a laser diagnostic instrument will be further developed for the diagnosis of bubbles due to cavitation in flow systems. The principle of the diagnostic method is phase doppler interferometry. Identification of particles as either solid or bubble, and determination of orientation and shape of bubbles, will be attempted with the new instrumentation first in preliminary validation experiments and then in actual cavitating conditions. Cavitating flow diagnosis will permit better understanding of, and development of better predictive models for, flows applicable in chemical engineering, nuclear engineering, and biological systems.

根据SBIR第二阶段赠款，激光诊断仪器 将进一步开发用于诊断气泡， 流动系统中的空穴现象。诊断的原则 方法是相位多普勒干涉法。鉴定 固体或气泡状颗粒，以及 气泡的方向和形状，将尝试与 新仪器首次进行初步验证 实验，然后在实际空化条件下。 空化流诊断将有助于更好地理解， 和开发更好的预测模型， 适用于化学工程、核工程， 生物系统。
