Dissertation Enhancement: Turbulence Modification in Particle-Laden Channel Flows

伊顿9908692本奖项支持授予斯坦福大学约翰·伊顿博士的国家科学基金会论文增强奖。伊顿博士的博士生安东尼·帕里斯先生将在日本横滨庆应义塾大学的久田光一教授的实验室工作六个月。该研究项目将研究空气和水通道流动中的湍流可以通过小分散颗粒的存在来改变的机制。尽管过去的研究发现，在充满颗粒的流动中，湍流水平可能会增加或减弱，但与这种湍流改变相关的物理机制仍然知之甚少。这项研究合作将汇集斯坦福大学和庆应义乌大学分别提供的用于研究槽流中湍流衰减和增强的独特设施。这项研究将为湍流模型师提供信息，促进颗粒流在工业应用中的使用，如颗粒传输、污染控制和煤粉燃烧。

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.***
