Abstract
Cavity flameholder is known as a promising technique to improve fuel mixing within the combustion chamber. This article studied the influences of the strut angle on the mixing performance of multi jets released inside the cavity flameholder. Finding the optimum jet configuration is done to promote the mixing performance of fuel through chamber when strut is applied in the upstream of the cavity flameholder. The impact of strut angle, fuel jet direction, and free-stream Mach number on the performance of three multi jets inside the chamber is disclosed in our research. For the simulation of our model, turbulent SST model is employed to obtain fuel distribution through the cavity. Our findings indicate that the counter jet is more operative in mixing of the fuel than co-jet since the main circulation is close to counter-jet, and fuel could efficiently distribute by the main circulation.
