Dissertation Enhancement: Turbulence Modification in Particle-Laden Channel Flows

该奖项支持美国国家科学基金会论文增强奖，授予斯坦福大学的约翰·伊顿博士。Eaton博士的博士生Anthony Paris先生将在日本横滨庆应义塾大学Koichi Hishida教授的实验室工作6个月。该研究项目将调查空气和水道流动中的湍流可能被小分散颗粒的存在所改变的机制。虽然过去的研究发现，在充满颗粒的流动中，湍流水平可能会增强或减弱，但与这种湍流变化相关的物理学仍然知之甚少。这项研究合作将汇集斯坦福大学和庆应义塾大学的独特设施，分别用于研究湍流衰减和通道流动的增强。该研究将为湍流建模者提供信息，有助于在工业应用中使用颗粒流，如颗粒输送，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.***
