Development of Kinetic-Approach-Based Two-Fluid Models for Two-Phase Turbulent Flows

摘要：0237951F。马沙耶克大学修订后的提案的重点是发展模拟含颗粒气体流动、分散两相流动的DNS和RANS方法。该结果将在固体粉末或液滴喷雾的湍流环境燃烧中得到广泛的应用，并计划在模拟中考虑传热和可压缩流动的影响。这个项目将建立在PI for LES湍流两相流模型的最新工作的基础上，并将为预测比目前更可靠的湍流颗粒流提供工程工具。该项目的一个关键内容是使用粒子相空间的概率密度函数(PDF)，并使用Louiville方程作为推导LES和RANS模型的起点。

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.
