Dilute turbulent gas-solid flow with particle interactions and turbulence modulation.

摘要

In this thesis, a mathematical model for the description of the hydrodynamics of dilute turbulent gas-solid suspensions is developed. The gas and particle flow fields are resolved in an Eulerian frame of reference. The model, which expands on previous work by Sinclair and Jackson;The gas turbulence is modeled by a single-phase k-;The model, developed for a general coordinate system, is applied to the case of steady, fully-developed flow in a vertical pipe. Comparisons of the model predictions with experimental data reveal that the resulting theory captures many of the reported flow features. The comparisons also identify aspects of the model to be improved. ftn
