Turbulence Structure of Two-Phase Jets

Chapter 1 provides a general overview and introduction of the principles and techniques of physical and mathematical modeling discussed in the book. It provides the rationale for modeling two-phase flow in gas-agitated reactors of materials processes. Chapter 2 presents the turbulence structure of two-phase jets and the impact on the mixing and chemical reaction rates in materials reactors agitated by... 

Many experimental studies have been carried out to investigate the turbulence characteristics in gas-liquid and gas-solid two-phase jets under various flow conditions [31-35]. In single-phase jets, turbulence is produced mainly by entrainment of surrounding fluid into the jets, [29,30] while in two-phase jets, turbulence production takes place also in the wake of bubbles or solid particles in addition to turbulence production due to the entrainment typical of single-phase jets. The size and shape of bubbles or soUd particles are considered to affect the structure of turbulence [36,37]. The effects of the size of bubbles or solid particles on the modulation of turbulence characteristics have been reported by many researchers [35-38]. However, the information on the effect of bubble shape is quite limited.
