DescriptionDescription: Serve as a Research AST, Fluid Physics engineer in the Computational Aerosciences Branch of the Research Directorate. The branch performs research in computational fluid dynamics (CFD) and computational aeroacoustics to improve the fundamental understanding of physics associated with the fluid mechanics and noise generation for complex aerospace systems.
Duties
The duties described below are at the full-performance level. Duties assigned at a lower grade level will be of more limited scope, performed with less independence and limited complexity; duties will be commensurate with the grade of selected employee.
• Develop, apply, and validate computational methods for the prediction of the radiated noise from unsteady flow simulations.
• Apply advanced simulation techniques on high-performance-computing resources to extend the physical understanding of noise generation mechanisms and apply concepts to reduce the radiated noise.
• 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.

• US citizenship or permanent resident status is a bona fide requirement.
Desired Skills:
• PhD preferred
• Knowledge of fluid mechanics, numerical methods, and/or physical modeling techniques.
Company DescriptionAbout NASA and the Computational AeroSciences Branch – The advertised position will reside in the Computational AeroSciences Branch (CASB) in the Research and Technology Directorate at NASA Langley Research Center (Langley Research Center | NASA) in Hampton, Virginia. The branch mission is to develop and apply aerodynamic and acoustic simulations methods for aerospace vehicles with applications in all speed regimes, from subsonic to hypersonic flight. The branch works to improve the fundamental understanding of physics associated with the fluid mechanics (e.g., transition and turbulence) and noise generation for complex aerospace systems. Research is carried out to develop new physics-based prediction methods and extensions of existing methods for the analysis and design of complex three-dimensional configurations, including verification, validation and the use of massively parallel high-performance computing architectures. Of particular interest is research to develop advanced techniques and models for the prediction and control of turbulent flows, with an emphasis on the high Reynolds number flows encountered on full-scale aircraft configurations. Objectives of the research conducted in the branch include: to advance the state-of-the art of CFD for efficiency, accuracy and robustness; flow control; efficient design of aerospace vehicles; methods for airframe noise prediction and control of noise sources. Research is accomplished through problem formulation, computational and experimental studies, analyses, documentation, and the dissemination of results from various research studies.
