AN ABSTRACT OF THE THESIS OF Andrew John Cihonski for the degree of Master of Science in
 

Summary:  AN ABSTRACT OF THE THESIS OF
Andrew John Cihonski for the degree of Master of Science in
Mechanical Engineering presented on October 15, 2010.
Title: Investigation of volumetric coupling effects on particle-laden
turbulent flows at dilute to moderate loadings
Abstract approved:
Sourabh V. Apte
Particle-laden turbulent flows are of great importance in many industrial
applications and are sufficiently complex to require multiple methods of study to
provide a better understanding of the dominant physical mechanisms present in
these processes. This work on large-eddy simulation of particle-laden flows seeks
to help provide the building blocks for larger scale models to be used in design
scale analysis of industrial processes such as oxy-coal combustion power plants.
Presented in this work are a series of studies related to real world particle-laden
turbulent flows of practical importance, such as a particle-laden slot nozzle jet
and a particle-laden channel flow at various mass loadings. The features of the
particle-laden turbulent channel flow and an in depth analysis of the effects of
accounting for the finite-volume of the particles is presented. Finite-volume
effects are analyzed for changes in turbulent statistics as well as particle
structuring. General agreement with previously published results is found and
