As a Research Aerospace Engineer, AST, Fluid Mechanics in the NASA Advanced Supercomputing Division (NAS) at Ames Research Center, you will leverage cutting-edge physics-based modeling methods to enhance capabilities within the computational fluid dynamics (CFD) solver framework developed in-house. You will lead efforts to predict next-generation flight vehicle characteristics using high-fidelity CFD methods to reduce program cost and ensure mission safety and success.

Duties

Utilizes an understanding of the physics of flow phenomena and physical models to assist in improving the methodology for calculating the flow of fluids through or about aircraft, spacecraft, entry vehicles, etc., and their components. Assists with conducting specialized studies on flight vehicles utilizing high-fidelity computational fluid dynamics (CFD) methods, including overall and individual major systems components for safety, suitability, and effectiveness in operation. Assists in the development of novel and existing high-fidelity capabilities within the CFD workflow, which contribute to the pre-processing, simulation, and post-processing of large-scale simulations and aerodynamic databases. Develops and maintains machine-learning (ML) tools that automate or reduce work load for running CFD simulations and assembling large-scale aerodynamic databases. Generates water-tight unstructured surface meshes starting from imperfect Computer-Aided Engineering models and creates overset structured grids for OVERFLOW using Chimera Grid Tools. Documents analysis results through technical reports and communicates findings through publications and periodic briefings. Fosters 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.
