Description

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

• 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.
• 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.
• Duties may include monitoring and evaluating research contracts and grants to 
accomplish collaborative research with external organizations.


Requirements

• MS in engineering, applied mathematics, computer science, physics, or 
equivalent, with strong background in with high fidelity numerical simulations 
(i.e., 
computational fluid dynamics (CFD)) to analyze aerospace vehicles and components 
such as commercial/military aircraft, space transportation systems, launch 
vehicles; working with unsteady fluid dynamics (e.g., acoustic noise generation, 
separated flows); writing, reporting, and presenting results to include 
publications.

• A desire to quickly learn and apply new paradigms relevant to current and 
emerging computational methods, and an eagerness to work in a team environment.

• Ability to successfully complete a background investigation required to obtain 
a NASA badge.

• 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 Description

About 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 for development of 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 the 
formulation, conduct, analysis, correlation, documentation, and dissemination of 
results from various research studies.
