Turbulence Modeling Postdoc
- Req. Number: IRC129599
- Organization : XCP-4/Continuum Models and Numerical Methods
- City, State: Los Alamos, New Mexico
What You Will Do
We are looking for a postdoc to help advance the frontiers of the modeling of turbulent mixing. Los Alamos is engaged in wide-ranging research in the modeling of turbulence, including Reynolds-averaged Navier-Stokes (RANS) models, large-eddy simulation (LES), and hybrid modeling. Depending on the candidates skills and interests, the work could include probability density function (PDF) methods, stochastic differential equations, dynamical systems approaches to turbulence, and looking at the interaction of turbulence with other physics including combustion, radiation transport, and magneto-hydrodynamic or plasma turbulence. The successful candidate will participate in the theoretical development of new models, implementation in LANL multiphysics codes, and validating against experimental data. The project will include collaboration with our world class scientists in turbulent mixing in extreme conditions, LANL code teams, and DOE experimentalists working at our unique high-energy density experimental facilities.
What You Need
Minimum Job Requirements:
Turbulence Modeling
Research experience in the modeling, theory, or simulation of turbulence using RANS, LES, or hybrid methods.
Computational Fluid Dynamics
The individual should be have programming experience working in computation fluid dynamics codes. You will need to be familiar with at least one of: C++, Fortran, or Python.
Mathematics
Demonstrated proficiency in mathematical techniques in fluid dynamics.
Communication and Collaboration
Verbal and written communication skills are critical for this position. In addition to scientific publication and conference presentations, you will be expected to educate LANL staff about your research and work collaboratively to apply it to problems of LANL interest.
Continuous Learning
This position involves developing novel research tools and applying them in new ways. The successful candidate needs to demonstrate initiative for continuous learning and skill development as an approach to new challenges.
Education/Experience:
Ph.D. in Engineering, Physics, Mathematics, or related field, in the area of fluid dynamics, completed within the last five years or soon to be completed.
Desired Qualifications:
Turbulence Model Development
Candidates with research experience in developing new predictive engineering models for turbulent flows are strongly preferred.
Variable Density Flows
It would be nice if you have experience with variable density flows, either multi-species mixing or highly compressible flows.
Mathematical Methods
Experience in any of the following would be a plus: reduced-order modeling, stochastic and PDF methods, or dynamical systems.
Turbulence Multiphysics
Research experience in the interaction between turbulence and other physics processes is a plus. This could include, combustion (including thermonuclear burn), radiation transport, magneto-hydrodynamics, and turbulent plasmas.
High-Performance Scientific Computing
Experience in scientific computing is a plus, especially any of the following: modern software engineering practices and tools, high-performance optimization including MPI and GPU programming, or being part of a code development team.
Clearance
It would be a plus if you are able to obtain a Q clearance, which typically requires US citizenship.
Work Location: The work location for this position is onsite and located in Los Alamos, NM. All work locations are at the discretion of management.
Salary: Competitive salaries are based on the date the PhD degree requirements were completed or the degree was awarded. Starting salary for a new graduate is currently $94,500.

Additional Details
Directive 206.2 - Employment with Triad requires a favorable decision by NNSA indicating employee is suitable under NNSA Supplemental Directive 206.2. Please note that this requirement applies only to citizens of the United States. Foreign nationals are subject to a similar requirement under DOE Order 142.3A.
Q Clearance: Selected applicants will be subject to a background investigation conducted by or on behalf of the Federal Government, and must meet eligibility requirements* for access to classified matter. This position requires a Q clearance. and obtaining such clearance requires US Citizenship except in extremely rare circumstances. Dependent upon the position, additional authorization to access classified information may be required, which may or may not be available to dual citizens. Receipt of a Q clearance and additional access authorization ultimately is a decision of the Federal Government and not of Triad.
*Eligibility requirements: To obtain a clearance, an individual must be at least 18 years of age; U.S. citizenship is required except in very limited circumstances. See DOE Order 472.2 for additional information.
New-Employment Drug Test: The Laboratory requires successful applicants to complete a new-employment drug test and maintains a substance abuse policy that includes random drug testing. Although New Mexico and other states have legalized the use of marijuana, use and possession of marijuana remain illegal under federal law. A positive drug test for marijuana will result in termination of employment, even if the use was pre-offer.
Equal Opportunity: Los Alamos National Laboratory is an equal opportunity employer and supports a diverse and inclusive workforce. All employment practices are based on qualification and merit, without regard to race, color, national origin, ancestry, religion, age, sex, gender identity, sexual orientation, marital status or spousal affiliation, physical or mental disability, medical conditions, pregnancy, status as a protected veteran, genetic information, or citizenship within the limits imposed by federal laws and regulations.
