Eaton 9908692This award supports a National Science Foundation Dissertation Enhancement award to Dr. John Eaton of Stanford University. Dr. Eaton's Ph.D. student, Mr. Anthony Paris, will work for six months in the laboratory of Professor Koichi Hishida of Keio University in Yokohama, Japan. The research project will investigate the mechanisms by which turbulence in air and water channel flows may be modified by the presence of small disperse particles.While past studies have found that turbulence levels may be augmented or attenuated in flows laden with particles, the physics associated with such turbulence modification remain poorly understood. This research collaboration will bring together the unique facilities for the investigation of turbulence attenuation and augmentation in channel flows available at Stanford University and Keio University, respectively. The research will provide information to turbulence modelers that should facilitate use of particle-laden flows in industrial applications such as particulate transport, pollution control, and pulverized coal combustion.***

伊顿9908692该奖项支持授予斯坦福大学的John Eaton博士的国家科学基金会论文增强奖。 伊顿博士的博士学位学生安东尼巴黎先生将在日本横滨庆应义塾大学的平田浩一教授的实验室工作六个月。 该研究项目将调查空气和水通道流动中的湍流可能因小分散颗粒的存在而被修改的机制。虽然过去的研究发现，湍流水平可能在充满颗粒的流动中被增强或减弱，但与这种湍流修改相关的物理仍然知之甚少。 这项研究合作将汇集斯坦福大学和庆应义塾大学分别提供的用于调查通道流中湍流衰减和增强的独特设施。 这项研究将为湍流建模者提供信息，这些信息将有助于在颗粒输送、污染控制和煤粉燃烧等工业应用中使用载有颗粒的流动。
