Effect of Side-Dump Angle on Outlet Parameters in A Side-Dump Simulator

In this study three-dimensional air mixing in side-dump combustor with fuel injectors whick located in quad rectangles side-dumps are numerically investigated. A comparison between side-dump combustors of 54 and 09 degrees have been done. Side-dump angle of 09 degrees is cross to the combustor simulator and the side-dump angle of 54 degrees is according to entrance stream. For the calculation a modified version of KIVA-3V code has been used. To investigate the flow, cold flow enters to the combustors simulators and fuel will be injected cross flow to the combustors. We have investigated the mean radius of outlet fuel droplets, outlet velocity and effective mass fraction in different initial conditions. The mass of fuel vapor inside the flammability range is named effective mass fraction. In accordance with results, the outlet velocity in side-dump angle of 54 degrees is more than side-dump of 09 degrees and radius of outlet fuel droplets in side-dump angle of 54 degrees is smaller than side-dump of 09 degrees
