Abstract

The interaction of two confined coaxial jets has been studied using Computational Fluid Dynamics. Annular jet flows over 8 flat blade swirl generator. Numerical simulation uses RNG k- ϵ turbulence model. These models are suitable for turbulent swirl dominated flows. Intermediate swirl injector has been simulated and the flow patterns for non-reactive and reactive cases are contrasted. Low swirling injectors do not promote the fluid to turn over near the center of the chamber, resulting larger mixing zones with weak gradients. Whereas large swirling flows promote the formation of an Inner Recirculation Zone that is a precursor of higher gradients. Probability Density Function is selected as combustion model. High swirl numbers let fix... (More)
