This dissertation is concerned with the numerical investigation of particle-laden flows. The simulations are based on a pseudo-spectral method to solve the fluid equations combined with a Lagrangian point-particle model for the particulate phase (Eulerian-Lagrangian approach).

โฆ Synopsis
This book develops the theoretical foundations of disperse two-phase flows, which are characterized by the existence of bubbles, droplets or solid particles finely dispersed in a carrier fluid, which can be a liquid or a gas. Chapters clarify many difficult subjects, including modeling of the interfacial area concentration. Basic knowledge of the subjects treated in this book is essential to practitioners of Computational Fluid Dynamics for two-phase flows in a variety of industrial and environmental settings.
The author provides a complete derivation of the basic equations, followed by more advanced subjects like turbulence equations for the two phases (continuous and disperse) and multi-size particulate flow modeling. As well as theoretical material, readers will discover chapters concerned with closure relations and numerical issues. Many physical models are presented, covering key subjects including heat and mass transfers between phases, interfacial forces and fluid particles coalescence and breakup, amongst others.
This book is highly suitable for students in the subject area, but may also be a useful reference text for more advanced scientists and engineers.

<p>This is an up-to-date review of recent advances in the study of two-phase flows, with focus on gas-liquid flows, liquid-liquid flows, and particle transport in turbulent flows. The book is divided into several chapters, which after introducing basic concepts lead the reader through a more complex
Proceedings of the Japan-US seminar on Two-Phase Flow Dynamics held in Japan, 1988. Papers are grouped into five categories: fundamental equations and closure laws; flow regime modeling and dynamics; phase separation and distribution phenomena; wave and shock phenomena and critical flows; and forced
