Statistical Treatment Of Turbulent Polydisperse Particle Systems

Statistical Treatment of Turbulent Polydisperse Particle Systems

In this book we will introduce the modeling process of turbulent particulate flows which are encountered in many engineering and environmental applications. These types of flows usually also involve heat and mass transfer and turbulence adds another dimension to the complexity of the problem and hence a rigorous mathematical treatment is usually required. This required mathematical background makes the learning curve for new research students and practicing engineers extremely steep. Therefore modeling process for new or existing problems is extremely slow and is usually restricted to minor improvements to the to the available models. In this book we try to gather the required mathematical knowledge and introduce them more intuitively. Many numerical simulations of basic processes and equation will be given to provide the reader with a physical understanding of the different terms in the underlying equations. We will start the modeling process from a mesoscopic level which deals with the system of an intermediate length scale between the size of the atoms or molecules and the bulk of the material. This provides a unique opportunity for the reader to intuitively add different phenomena to their models and equipped with the necessary mathematical tools derive the final models for their problems.

Turbulent Particle-Laden Gas Flows

Results are given of experimental and theoretical studies of "gas-solid particles" turbulent two-phase flows. Special emphasis is placed on studies of the behavior of particles suspended in a turbulent gas flow and their feedback effect on the characteristics of flow of the carrier phase. The characteristics of heterogeneous flows in channels (pipes) are analyzed, as well as those in the vicinity of the critical points of bodies subjected to flow and in the boundary layer developing on their surface. Problems of physical simulation of turbulent gas flows which carry solid particles are treated in detail. This monograph will be useful for researchers involved in investigations of gas dynamics and heat and mass transfer in multiphase flows, as well as for university professors, post-graduate students, and students.
