9601833 Petty A combined Doppler anemometer (PDA) and digital particle image velocimetry (PIV) system will be purchased with the dedicated HP workstations for supporting the ongoing basic and applied research of four faculty and their students. The measurement facility would (1) enhance the professional interactions of MSU researchers with their national and international colleagues; (2) provide new understanding of process equipment performance in terms of underlying flow phenomenon; and, (3) increase the knowledge base needed to validate multiphase flow models, turbulent closure theories, and rheological constitutive models for viscoelastic fluids. The specific research problems proposed for study during the three-year acquisition period two-and three-dimensional involve the-phase flows, reverse flows, secondary flows, flow transitions, and unsteady flows. Thus, the PDA/PIV system should yield new understanding of specific flow structures encountered in hydrocyclones, in automotive cooling fans, in piston/cylinder engines, and in reaction injection molding processes. ***

9601833 Petty A组合多普勒风速仪和数字粒子图像测速系统将与惠普的专用工作站一起购买，以支持四名教师及其学生正在进行的基础和应用研究。该测量设施将(1)加强密歇根州立大学研究人员与其国内和国际同行的专业互动；(2)根据潜在的流动现象，提供对过程设备性能的新理解；以及(3)增加验证粘弹性流体的多相流模型、湍流闭合理论和流变本构模型所需的知识库。建议在三年采集期内研究的具体研究问题包括两维和三维流动，涉及相流、逆流、二次流、流动过渡和非恒定流。因此，PDA/PIV系统应该对水力旋流器、汽车冷却风扇、活塞/气缸发动机和反应注射成型过程中遇到的特定流动结构有新的理解。***
