The goal of this research is to numerically verify and validate available computational fluid dynamics (CFD) codes for use in modeling swirl-driven combustors, specifically the bidirectional vortex rocket engine. To that end, results from simulations run in SolidWorks Fluid Simulation, Ansys CFX, Ansys Fluent, and OpenFOAM will be compared to existing analytical models and experimental results. All software packages were found to capture the significant vortex structures to varying levels of accuracy. In addition to verifying and validating the CFD packages, we will also assess the usability of each, with an emphasis on swirl-driven applications. SolidWorks is found to be the most user-friendly of the packages, while OpenFOAM most closely matched the validating analytical solutions and provided extensive flexibility for a low cost.
