Summary Serve as a Senior Research AST, Fluid Mechanics engineer in the Computational AeroSciences Branch of the Research Directorate. The branch performs research in computational fluid dynamics (CFD) and transition modeling for high-speed flows. You will work with an established team of computational and experimental researchers, contributing to the development and application of physics-based CFD models to complex flow phenomena relevant to hypersonic vehicles. Responsibilities Develop, apply, and validate computational methods for the prediction and modeling of boundary layer transition in the hypersonic speed regime. Evaluate existing transition models for canonical hypersonic configurations and develop transition correlations for important scenarios relevant to the hypersonic vehicles. Develop the computational methodology to apply those correlations toward reliable, and preferably physics-based, predictions of high-speed transition. Evaluate comparisons of experimental and computational results and report the findings at technical conferences and in the scientific literature. Serve as a technical expert and interface with other researchers in industry, universities, NASA, and other government agencies. Formulate and conduct research in problem areas that are highly complex and of considerable scope working on problems that are often difficult to define and require novel approaches and sophisticated research techniques. Conduct research, interpret, and correlate results of high -fidelity numerical simulations (i.e., computational fluid dynamics (CFD)) and model high-speed flows associated with hypersonic vehicles. Foster a culture of engagement, diversity, inclusiveness, excellence and innovation. Champion NASA's commitment to Diversity, Equity, Inclusion and Accessibility to create an environment that promotes a commitment to safety, integrity, and teamwork.
