Investigation of volumetric coupling effects on particle-laden turbulent flows at dilute to moderate loadings

Graduation date: 2011Particle-laden turbulent flows are of great importance in many industrial\ud applications and are sufficiently complex to require multiple methods of study to\ud provide a better understanding of the dominant physical mechanisms present in\ud these processes. This work on large-eddy simulation of particle-laden flows seeks\ud to help provide the building blocks for larger scale models to be used in design\ud scale analysis of industrial processes such as oxy-coal combustion power plants.\ud Presented in this work are a series of studies related to real world particle-laden\ud turbulent flows of practical importance, such as a particle-laden slot nozzle jet\ud and a particle-laden channel flow at various mass loadings. The features of the\ud particle-laden turbulent channel flow and an in depth analysis of the effects of\ud accounting for the finite-volume of the particles is presented. Finite-volume\ud effects are analyzed for changes in turbulent statistics as well as particle\ud structuring. General agreement with previously published results is found and\ud expounded upon
