    abstract    = {Computational fluid dynamics (CFD) has become a vital tool for aerospace engineers. The ability to rapidly assess the performance of a design without a wind tunnel experiment or flight test has greatly increased the rate at which engineers can iterate on a design. Despite CFD's widespread adoption, its automated use remains challenging. One challenge is the development of robust and high-performance solver algorithms for a broad range of problems. Globalized Newton's methods offer a promising solution to this issue. However, selecting a suitable globalization strategy for this task requires careful analysis of possible candidates. In this work, we investigate the use of combinations of existing globalization strategies over a range of test cases. Specifically, we will compare the relative performance of combinations of pseudo-transient, boundary condition, and dissipation-based continuation. We find well tuned methods that use a mix of pseudo-transient and
                  dissipation-based continuation to be the most robust for our test problems.}
