ABSTRACTCTS-0237951F. Mashayek, Univ. of IL - ChicagoThe focus of the revised proposal in on development of DNS and RANS methods for simulation of particle laden gas flow, dispersed two-phase flows. The results will have broad applications to environmental combustion in turbulent flows with either solid powder or droplet sprays, and the plan is to include heat transfer and compressible flow effects in the simulations. This project will build on the recent work by the PI for LES models of turbulent two-phase flows and should provide engineering tools for the prediction of turbulent particulate flows that are more reliable than at present. A key element of the project is to use the probability density function (PDF) for particle phase space and to use the Louiville equation as the starting point for deriving the LES and RANS models.

摘要CTS-0237951 F。Mashayek，伊利诺伊大学芝加哥分校的修订建议的重点是发展DNS和RANS方法，用于模拟含颗粒的气体流动和分散的两相流动。 结果将有广泛的应用环境燃烧的湍流与固体粉末或液滴喷雾，该计划是包括传热和可压缩流的影响，在模拟。该项目将建立在最近的工作由PI的LES模型的湍流两相流，并应提供工程工具的预测湍流颗粒流，比目前更可靠。该项目的一个关键要素是使用粒子相空间的概率密度函数（PDF），并使用路易维尔方程作为推导LES和RANS模型的起点。
