N2 - The goal of this research was to use Star CCM+, a Computational Fluid Dynamics software, to parameterize the outlet on the bidirectional vortex engine. The outlet configurations that were used were 25, 50, 63, 675, and 707 percent of the base of the chamber for the diameter. In this work, the numerical results were compared to analytical solutions for agreement. As part of the parameterization, the velocities at the mid-plane of the chamber were compared for six outlet reconfigurations. The findings of the simulation have shown a trend of more swirl velocity the larger the outlet is in diameter, and the axial velocity magnitude at the centerline increases for larger openings. It was also shown that the swirl velocity peak moves radially outward as the outlet size increases. Multiple mantles, regions where the axial velocity is zero, were also observed in all cases except the case where the base of the chamber is completely open.
