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 treatment of the subjects. The reader will find an extensive review of both the older and the more recent literature, with abundance of formulas, correlations, graphs and tables. A comprehensive (though non exhaustive) list of bibliographic references is provided at the end of each chapter. The volume is especially indicated for researchers who would like to carry out experimental, theoretical or computational work on two-phase flows, as well as for professionals who wish to learn more about this topic.

This dissertation discusses some of the turbulence models employed here: an assumption that the turbulent viscosity of the dispersed phase equals that of the continuous phase; a two-phase modified k $-\varepsilon$ model used for both phases and another model with a variable turbulent Prandtl number (i.e., ratio of the turbulent viscosity of the distributed phase to that of the continuous phase) based on Tchen's theory (1947) of a particle in a turbulent stream.

A numerical model was developed to simulate one-dimensional, fully developed, steady, axisymmetric turublent bubbly flow. The two-equation (k-$) turbulence model as proposed by Lee was used, with enhancing modifications, to predict the turbulence in the liquid phase of the turbulent bubbly flow. The modifications were related to the selection of the numerical constants and the formulation of the bubble-induced turbulence generation and dissipation, allowing for improved predictive capability of the present model, when compared to the original work of Lee. The numerical predictions of the model are compared with available experimental data for one-dimensional, fully developed, steady and axisymmetric turbulent bubbly flow. The results indicate that the results of the prediction are in good agreement with the experimental data.

This book allows readers to tackle the challenges of turbulent flow problems with confidence. It covers the fundamentals of turbulence, various modeling approaches, and experimental studies. The fundamentals section includes isotropic turbulence and anistropic turbulence, turbulent flow dynamics, free shear layers, turbulent boundary layers and plumes. The modeling section focuses on topics such as eddy viscosity models, standard K-E Models, Direct Numerical Stimulation, Large Eddy Simulation, and their applications. The measurement of turbulent fluctuations experiments in isothermal and stratified turbulent flows are explored in the experimental methods section. Special topics include modeling of near wall turbulent flows, compressible turbulent flows, and more.
